First layer speed percentage ignored if autospeed is enabled

This might be a bug or just a case of insufficient documentation.
I have enabled autospeed in all speed fields and that works fine, limited by max print and volumetric speed. I would like the first layer to go slower for better bed adhesion so I set first layer speed to 50%, but that has no effect on the G-code. Using 100%, 50% or 10% doesn't seem to make any difference. I guess this could be expected when enabling autospeed, but to me setting the first layer speed should work as a multiplier for the calculated first layer speeds.

Of course I can acheive what I want with a post processing script but it seems like there already is field for this in the UI.

As a side note, setting an absolute speed in mm/s for the first layer works fine.

Any commennts? Is it a bug?

There is already an open issue regarding this topic: [github.com]
Also there is a workaround, but it means that you can't use percentages and have to enter a numeric value.

Thanks, I searched the issues but missed this since the title suggests it is related to skirt/brim. I see that he also had first layer speed as a percentage.
