Fast rewind jumps to negative time

Hi,

I am wondering if its just me, that if you start to watch a video and after a few seconds you press downwards or keep pressing left on the remote, the player jumps to a negative playtime and behaves weird…
I noticed that already a year ago at image
CoreELEC-Amlogic-ne.arm-20.2-Nexus-Generic.img
and its still there using image
CoreELEC-Amlogic-ne.aarch64-21.0-Omega-Generic.img

Is that a known bug?
