Unfortunately, I'm not able to replicate this behavior, so it may be a timing issue on the system.

That said, there are some possible debugging options that may make it easier to fix.

Apparently that was an issue with Karabiner, quiting it resolved the issue and now one shot mods are working fine in this regard. Thanks for your time in checking this!

lol, well, glad that you found the source of the issue, at least!

Just to clarify, this was just vanilla Karabiner, without any magic presets or functions, I was using it to debug keycodes for unrelated issues. Sounds like a bug in Karabiner
