[Bug] Key presses got discarded if the key is pressed to quickly (I think)

[Jacfger]

Type: Bug

Describe the bug
I have a qmk keyboard which defined a combo key. So to the best of my knowledge, it works by some kind of buffer is used when a combo key is pressed, and then if the next keycode isn't inside the combo key look up, both keycode would be sent simultaneously. But when this happens, the extra key can be discarded in vscode vim. For example, let's say the combo key is ac, and if I spam ax multiple times really quickly, what would ended up into the buffer would be aaaaaaaa, instead of axaxaxaxaxaxaxax.

To Reproduce
Steps to reproduce the behavior:

1. have a qmk keyboard with combo key defined.
2. spam one key with combo key defined, then press another that doesn't form combo with it.
3. some character would not be properly registered

Expected behavior
To have the key properly registered

Screenshots
no.
