[Bug] Different response of keyboard depending on key pressing speed in succesion .

[BartTych]

Describe the Bug

when i have Karabiner soft turned on i get a bit crazy response from keyboard depending on speed of pressing keys in succession.

slow press; fast press
<= ; <+

= ; >+
which is obviously annoying when writing code. after encountering the issue i tested different combinations
it does not happen for all key combinations but when it does it is consistent.

i have both keys in a layer defined as MO(_layer) which is active as long as layer activation key is pressed.

more examples as a clue what can be going under the hood:

slow press; fast press
(= ; (+
{= ; {+
#= ; #+
(5 ; (%
(4 ; ($
(3 ; (#
no influence examples:
[= ; [=

the issue goes away when karabinier soft is inactive but that is not a long term solution since I want to change layout of mac keyboard and use external keyboard with qmk soft
