Random ghost inputs from remapped buttons (Bazzite)

[nextproblemreporter]

I noticed that I sometimes get ghost inputs from the extra buttons (that steam doesn‘t see) which are remapped to keyboard. For example I have LM mapped to KEY_I and in Spacemarine two I had this key assigned to open text chat and every half hour it opened without me pressing that button. I‘m sure I didn‘t hit it by accident because this also happens when I don‘t touch the controller at all, even in desktop mode I had it writing these remapped buttons into textfields without me touching the controller.

I added regression coverage for this path in #305, and the test confirms idle/unrelated Vader 5 reports do not emit ghost aux key events.\n\nPlease retest on latest. If it still happens while the controller is untouched, please attach a dump export so we can tell whether the physical report bit is actually flipping or whether the mapper is generating it.
