Did you observed it with evemu or with libinput? Please use former as it
connects directly to input device and gives raw data.

I recently implemented evdev support for consumer page for bluetooth keyboards
(not publicly available yet) and found out that my bt-keyboard loses *release*
events on simultaneous presses as it is unable to report "which key has been
depressed" at HID-protocol level. It is capable only to say that "last/all key
has been depressed" so my driver has to generate release event at next
interrupt at his own. I do not see how your patch does such "autorelease".
Maybe ukbd does this automagically? I should look deeper in its internals.
Unfortunately I cant do hardware testing now
