Issue persists in OpenBSD 7.6, tor-browser-14.0.9

Created an account just to add to this.
Am experiencing the very same issue on Arch Linux x86_64, kernel 6.15.6-arch1-1.
To replicate: I just surf the net with TorBrowser (v14.5.4 ), eventually decide to eg: save some file (with all due security drawbacks) and the Save To dialog will get borked as per the BSD user’s screenshot.
In my case, my system is short on RAM and can crash X11 if I have other stuff open, as the dialog quickly eats up memory.
Executing TorBrowser via terminal allowed me to intercept these errors:

While the crash of X11 left this trace in my journalctl:

Jul 16 08:42:42 hostname kernel: Out of memory: Killed process 11650 (Xorg) total-vm:4822580kB, anon-rss:3775256kB, file-rss:636kB, shmem-rss:47696kB, UID:1000 pgtables:7940kB oom_score_adj:0

My system is running the i3 window manager in tiling configuration, it is possible something goes wrong while getting the properties for the dialog? My other system apps don’t share the behavior (I tried with firefox 140.0.4 (64-bit) and it works properly).
