I set up a keyboard automation that can reproduce this every time on Minecraft 1.18.1.
I did some testing, and found out that 1.12.2 and earlier are completely unaffected, while versions starting from the first 1.13 snapshot, 17w43a, are affected. This was the first snapshot that came with LWJGL 3.1.2.
The workaround by settings XMODIFIERS doesn't seem to fix it for me (although I only tested this on 1.18.1).
