R5 Mark II: Can't set very short exposures times in AV

[emonk]

One of the reasons I purchased the R5 Mark II was the very short exposure times when using e-shutter. However, I usually use AV and was surprised to find out that when using this mode, I can't use exposure times shorter than 1/8000sec. 

Why was this limit set? Can it be removed (without switching to Tv or M)?

Greetings,

Please see C.Fn Exposure. > Set shutter speed range for an explanation.

In [P] or [Av] mode, or in [Fv] mode with shutter speed set to [AUTO], the shutter speed is set automatically within your specified range (except for movie recording).

I'm sorry, but this is not a solution. Set the camera to electronic shutter, Av and very high ISO value, open the aperture and point it at bright source of light. You will see that instead of dropping to shorter exposure than 1/8000, the time display blinks and does not go further down. Only on M and Tv modes you can (manually) set it to anything shorter.
