text get missing in older doc file

As you can see, both MSO and LO support linked textbox, where text can flow from one box into the other. With doc files, everything works fine if not perfect, until the textboxes are GROUPED. Depending on the MSO version, the file in question is saved with, grouped and linked text boxes may get UNLINKed in different ways, in some case the text is missing in a unrecoverable fashion, which is worse than messed layout.

For doc files created from MSO 2003 and previous,
the text flows are broken into corresponding grouped but unlinked text boxes in LO. This could have been acceptable for viewers. But this breaking process consumes 1 character each time it breaks a text flow, which means every previously linked textbox got one trailing character missing, except the last box. And there doesn't seem to be a way to recover this missing text in LO along. (see attachment for example )

For doc files generated by MSO 2007 (and above?), Grouped Linked Textbox got unlinked, and all the text is crammed into the first textbox in LO. Other textbox got empty. Besides the first textbox is expanded vertically for as long as necessary to avoid text overflow, which messed up the layout.

With docx file , all linked textbox are broken in LO. The Grouped ones are merged and enlarged horizontally in a uncontrolled way beyond the page border. Not grouped but linked ones become empty except the first textbox with overflowed text hidden.

As you may have noticed in daily publications, linked textbox is a very basic and common tool in desktop publishing. And missing text is a real deal breaker. 
We really need it to work correctly. Please fix this feature in doc format.

Thank you,

MSO 2003 Linked Textbox sample

English text looks alright, since only white space and line-breaker is bitten off.
But when double byte Characters get bitten off like with white-space and paragraph line-breaker, we start missing text with CJK lanugage.

In Bug 87348 I marked it as pre-bibisect.   For the .docx part of this bug at least, it appears that it has never worked.

Just verified (using bug 87348 sample LinkedFramesBug.docx) that docx doesn't flow on versions:
-oldest (3.5.0): doesn't really support textboxes at all.
-last36onmaster: 3 textboxes shown - all text in the first box
-last40onmaster: no textbox or text seen at all
-last41onmaster: same as 3.6
-last42onmaster: same as 3.6
-last43onmaster: same as 3.6

Let's track the .docx issue here. The .doc issue exposed by attachment 91861 [details] was spun off into Bug 120755.

How it looks in Writer 7.4 (resaved in mso)

This ticked has two cases:
1) VML groupshape (v:group) with linked feature >> still missing feature, but VML deprecated
2) DrawingML equivalent (resaved with word 19) >> Works with patch, as in my screenshot (Gerrit: https://gerrit.libreoffice.org/c/core/+/130283)

Comment 16 László Németh 2022-03-29 14:28:12 UTC
Fixed for DOCX in https://gerrit.libreoffice.org/c/core/+/130950. For DOC, there is a workaround to convert it to DOCX/DrawingML by MSO, so I suggest to close this issue, and file a new one for DOC, if needed.

@Attila: thanks for the fix!

@Wilson, Buovjaga, Justin, Luke: thanks for the bug report and bug handling!
