Line spacing display test
In Normal View (page view), line spacing is unchanged regardless of zoom level - as expected.
In Web View, line spacing is always less than in normal view, and the spacing changes depending on the zoom level. 100% zoom is particularly bad.
This problem got much worse from version 5.3
In the example file I have added a rectangle to left of the text so that one can easily see the relative size changes between text and graphic object.
To view the problem, change zoom level while in Web View, then do the same in Normal View.
This looks to be to be the same problem as reported in Bug 105860 for Calc.
Examining that Calc problem, it too exhibits the same behaviour in that
(a) the line spacing at 100% zoom reduced in LibO 126.96.36.199 compared to previous
(b) the line spacing changes depending on the zoom
(c) 100% zoom seems to have the smallest line spacing
Depending on the document and font, the visual difference between 188.8.131.52 and previous is very obvious. A document that once had nicely spaced lines now looks cramped.
Ok, let's close as dupe then.

Dale, I think zooming is another problem which is older than the 5.3 regressions. Make a search or you find a bug in https://bugs.documentfoundation.org/showdependencytree.cgi?id=107923&hide_resolved=1
This bug was closed shortly after being created, marked as a duplicate of Bug 105860. That bug has been superseded by Bug 108891 - which no longer addresses the problem reported here. Therefore I am reopening this bug.
Khaled Hosny has done good work to fix how line spacing is calculated - implemented in version 5.3. I am sure he has achieved that for the issues he was dealing with.
However, his work appears to only address the rendering of text onto a page.
The problem I and many Calc users are seeing appears to be in the calculation of line spacing when the text is being rendered in abstraction - where the text is NOT being shown in the context of a physical page. In that situation there seems to be a completely different calculation being used for line spacing, and it is affected by the *zoom percentage*. The calculation differences become particularly noticeable when there are associated elements that are assigned a physical size e.g. row height in a Writer table or Calc cell.
*This* line-spacing calculation problem has existed for a long time, but has become worse and much more noticeable from version 5.3

Hey, with Caolán's work on bug 107249 please recheck with a current master > 20170906. Think this is also resolved now with backports in works for 5.4 and 5.3
(In reply to V Stuart Foote from comment #10)
Just checked and with the 20170906 TB39 Windows x86 build of master, the web view holds its formatting. Does not exactly match the left rectangles, but not sure the line heights would as there are multiple roundings of text to one of the rectangle when canvas is scaled.
I'd say Resolved Fixed.
Yes, let's put it to RESOLVED FIXED

As the OP, I can say the problem I reported has not been fixed.
The behaviour has been restored to be very similar to what it was pre version 5.3
This is definitely an improvement.
However, the faithful, near perfect handling of scaling, line size etc that exists in normal view has not been implemented in web view.

In Bugzilla, we deal with one issue per report. Let's agree that this was about the regression in 5.3 and you can open a new report for the older, underlying issue.
In the new report, you don't even have to re-upload your test file: simply refer to it like this: download attachment 134217 [details] and open it.
A nice-to-have in the new report would be a comparison screenshot of normal view vs. web view.
