[MU3.6.2_backend Issue] Lyrics with a melisma across a system break protrude the system, into the page border

[Jojo-Schmitz]

Describe the bug
Lyrics with a melisma across a system break protrude the system, into the page border

To Reproduce
Steps to reproduce the behavior:

1. in 3.6.2 have a score with lyrics and melismas.
2. Make sure at least one of those melismas crosses a system break (with the syllable before it being on the last note of the previous measure).
3. File > Save online.
4. See the error when viewing the score on musescore.com.
5. (Alternatively use the artifacts from [MU3] Fix GH#7449: Almost everything suitable for 3.6.3 or 3.7.0 #9000 and see the issue even locally).

Expected behavior
The lyrics' right edge should not protrude into the page border

Screenshots

Desktop (please complete the following information):

• OS: Any desktop version that includes those 3.6.2_backend fixes (there is no official one), namely those from [MU3] Fix GH#7449: Almost everything suitable for 3.6.3 or 3.7.0 #9000
• But the main point of this issue is the backend on musescore.com

Additional context
The culprit probably is #8296, but could also be #8176 or #8461
As far as I can tell none of those have yet been ported over to master, but as soon as that happens, that branch would also be affected. See also #9581, the first part of porting all those 3.6.2_backend fixes over to master

There's another and related issue, see #9000 (comment)
There lyrics with some (negative) ticks and/or ticks_f like this

          <Chord>
            <durationType>16th</durationType>
            <Lyrics>
              <ticks>-1800</ticks>
              <ticks_f>-15/16</ticks_f>
              <text>lyric</text>
              </Lyrics>
            <Note>
              <pitch>62</pitch>
              <tpc>16</tpc>
              </Note>
            </Chord>

settings destroy the layout quite badly.
It is completely unclear though (to me at least), how those came about.

Examples for both issues in https://musescore.com/user/23930/scores/7122651/s/LO8Qg1
1st issue at several places, measures 5, 15, 18, 21, 26, 51, 54 (here the Dynamics are manually set off, so not part of the problem).
2nd issue at measure 28.

Original reporter here -- the score (with negative tick values) was created in a release version of MuseScore 3, "3.6.2.548021803". Unfortunately, my friend who created it has no idea how she managed that, and I have no insight into reproducing that specific aspect.

[Jojo-Schmitz]

The workaround for that 2nd issue is quite easy: double click the next lyrics after the broken one, Press Shift+Space to move to the previous note, press _ to add the missing melisma and the layout looks fine again (well, except for the 1st issue)

[Tantacrul]

@oktophonie - is this one we think is fixed in MS4? Or will we (as I suspect) need to wait for MuseScore.com uploads before knowing?

[Jojo-Schmitz]

This might meanwhile be an issue with 3.6.2_backend_musicxml rather than 3.6.2_backend and as such no longer actual?

[Tantacrul]

OK, closing for now (unless there is an objection). I don't see us fixing this in favour of focusing on uploads from MS4.
