RocqIDE crashes after the "Find" feature is used exactly 61 times

Description of the problem

I am using Coq and Rocq on a Windows laptop (Windows 11). I've been having trouble with CoqIDE and RocqIDE crashing a lot, similar to this bug report which was closed but not really resolved. I realized that the issue seemed to be exacerbated by the "Find" or "Search" functionality (i.e. what appears when you hit Ctrl-F, not the "Search" command in the code). And indeed, this seems to be the root cause.

After some testing, I realized that the bug is extremely reproducible: open any .v file, open up the "Find" window, put anything in the search box (e.g. even a single character), and click "Next" exactly 61 times. Every time, on the 61st click, RocqIDE freezes up and needs to be shut down and restarted.

Can't reproduce on Linux (tested 8.19.2, 9.0.1 and 9.1.0) so this is probably Windows-specific.

I also just tested it on a Mac and couldn't reproduce it, so I'd agree that it's probably Windows-specific. I haven't yet been able to get my hands on a second Windows computer to try to reproduce it there.

I could reproduce using the Rocq Platform 9.0 installer. I also installed 9.1.0 through opam but that one was just generally unstable, merely hovering over the top icons would be enough to crash it.
