Description Telesto 2025-06-30 17:59:17 UTC 
Description:
Underlining certain text part, shows substantial change in justified text distribution and undo doesn't restore the old situation

Steps to Reproduce:
1. Open the attached file
2. Double (left) click "Ipsum" in the last line
3. Press CTRL+U (or underline button)
4. Notice the last line shrinking (substantially)
5. Press CTRL+Z. Not the text not expanding (as much)

Actual Results:
* The last line shrinking (substantially)
* Undo isn't restoring 

Expected Results:
No substantial shift in text distribution. Or at least is should be consistent (so Undo restoring the 'old' situation)


Reproducible: Always

Notice the , at last line being aligned with right border line.

You can see a different 'Justified' when when pressing Underline.
