SUMMARY
I use Fedora with KDE Plasma on Wayland. I takes notes in Obsidian (Electron based) and copied a large JSON literal into the clipboard. I have pasted that into a textarea on an internal website. When I submit the form Plasma Shell crashes. According to the syslog, the issue seems to be within KWin.

STEPS TO REPRODUCE
1. Open internal website which has a form with a textarea.
2. Copy and paste large JSON literal from note taking program into the website.
3. Submit the form.

OBSERVED RESULT
Plasma Shell crashes when I submit the form.

EXPECTED RESULT
Plasma Shell doesn't crash.
