I want this ticket to be sort of "summing up" one, which would have the maximum of pertinent keywords (so, show up in searches and new issues' forms), and correctly formulate the problem, too.
When LO/OOO exports the document with formula(s) to MS Word .doc format, two important transformations should be done:
1) 'Fonts size' set of settings for each formula must be transformed into the respective MS Word MathType object set of settings.
2) Rendered formula(s) image(s) of acceptable quality should be put into the exported .doc.
* two simple ODT with A^b formula (one in 14pt, one in 8pt) and some 14pt text, all in Times New Roman
* two respective exported DOCs
* two snapshots of what MS Word 2003 shows when those DOCs are opened
* two snapshots of what MS Word 2003 shows when those DOCs are opened AND formula is double-clicked (opened for editing) and closed (Escape key) without making any changes
** At the moment of testing the MS Word installation had its default settings for MathType objects font sizes as 10pt for formula body text and 7pt for "big" superscript
On proofpics one can see that:
1bad) ODT 'Fonts size' data is either ignored or placed into the .doc in a wrong way -- after re-rendering formulas in Word (opening/closing; two snapshots with *_post_doubleclick* in names) the size is obviously something like 10pt in all cases
** this might or might be not worked around by re-setting MS Word default MathType objects' font sizes before opening the LO-exported DOC (I didn't test this yet)
2bad) LO puts the exported rendered image frame too high w/r to the baseline of the paragraph the formula is in (compare the respective *_before_doubleclick* and *_post_doubleclick* pairs)
** this necessitates double-clicking every formula in Word after every export (grand PITA!!)

And it will be very, very difficult to solve, without an access to some good docs on storage of 'Microsoft Equation 3.0' objects' properties -- that is, not MathType objects /per se/, but their wrappings inside the .DOC container. Even the placement of those things isn't readily evident. I couldn't find it, at least -- seems to be not stored in raw, but, guessing, as a some kind of diff.
Haha, I think I've got it! Seems Word 2003 does NOT store anything about the concrete settings according to which the actual processing (rendering) of MathType objects is done!
I've just made a series of .DOCs each consisting of one (and the same) empty formula only, changing only one aspect (one font face in styles, one pointsize in sizes) of Equation Editor, then 'saving as' under a different name. Lots of changes inside of those .DOCs, regardless of nothing being really changed (excepting the timestamp).
However, any of those .DOCS (re-)opens to the Eq. Editor style/size settings as set at last time, not as set when saving the .DOC. So, it looks like the .DOC file just doesn't contain any information on font/size setting for formulas rendering -- the Word installation does (at least, it is so in Word 2003 I have access to).
I hope this this little experiment proves that sizing the imported formulas to the 12/8 combination with `eqn` instructions 'size 12' and 'size 8' is unnecessary, counter-productive, indeed. So the whole business with 'size 12' and 'size 8' should be excluded from LO starmath module, just like I've been suggesting for years in https://bugs.documentfoundation.org/show_bug.cgi?id=45284
I believe this leaves only the matter of previews with lower edge shifted up.

Please look into that problem, guys. The StarMath/MathType object preview 'shifting up' in exported DOC is quite a showstopper, one has to reclick every individual formula in Word (and keep Word at hand, for that matter).
I've tried to do something myself, honest, but actually I'm not capable even of finding the code which positions the exported preview (incorrectly).
The dimensions of the preview itself generated subtly out of expected proportion are secondary to this.

If you have time, please do the following:
Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/
If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.
Please DO NOT

Issue still there. Is there a need to attach a proofdoc?
Can't test in 184.108.40.206, as the appimage variant crashes immediately after adding, editing and exiting the edit mode of the math object.

There are already a million attachments in this report, so no.
Of course the issue's still there.

PS You'll notice I've used the 'gen' VCL plugin, because the 'gtk' one requires wayland now, and I don't even have that thing installed.

Generally this is not true. Maybe your Linux distribution has some weird dependency set up.
Dunno about 'generally'. Specifically, I'm getting this:
/opt/libreoffice6.2/program/soffice.bin: symbol lookup error: /opt/libreoffice6.2/program/libvclplug_gtk3lo.so: undefined symbol: gdk_wayland_display_get_type
I'm not re-fetching the 6.3 appimage, but it looked the same with that.
...ah, and to clear the name of my distro :) -- the tail of 'ldd -r libvclplug_gtk3lo.so' output:
