App crashes while editing math equations in .docx

[visvaldas01]

This issue is unique.

• [X] I have used the search tool and did not find an issue describing my bug.

Operating System

Linux (DEB package)

Version information

7.3.0-1

Expected Behavior

I was editing a math equation in text, accidentally pressed Shift+Home and the left arrow, after which I expected it just to move to the start of the line.

Actual Behavior

The app just crashed with this error. After that it became only able for viewing and saving, but not editing.

Reproduction Steps

I clicked Insert -> Equation/Insert Equation -> Brackets -> Binomial coefficient, got into the formula from the right, pressed Shift+Home and the left (although it works with any) arrow. It also works with combinations like Ctrl+Shift+Left/Right - you should just highlight the whole formula and press an arrow (not a left click, it won't work!). BTW, Shift+Home doesn't work with a formula with an overbar (e.g. Accents -> ABC with overbar) if the cursor is not under the bar.

Additional information

I'm on Manjaro 22.0.4 Sikaris with x86_64 Linux 5.15.94-1-MANJARO kernel, using the onlyoffice-desktopeditors from the community repository (I checked that bug happens on onlyoffice-bin from the AUR too). I've managed to reproduce this error on virtual machine with Ubuntu 22.04.

onlyoffice --ascdesktop-support-debug-info output:

(This QXcbConnection output was printed after I closed the window)
