This is expected behavior in vim if you type wrEscion in insert mode

I don't type Esc key.
From that gif I've provided, you can see that no letter has been swallowed by Command mode

@sevenmaxis Can you give the exact key sequence you're typing? Also, is this consistently reproducible or is it sporadic?

@J-Fields Hi,
Yes, it happened sporadically, and there's no exact sequence I can notice. Also, it happened when I typing fast enough.
