Hi,

I have managed to reproduce this issue on latest FF release 72.0.1, Beta 73.0b4 and latest Nightly build 74.0a1 (2020-01-13) using Windows 10.
Further, I will move this over to a component so developers can take a look over it. If this is not the correct component please feel free to change it to an appropriate one.
The issue is not reproducible on Chrome.

Thanks for the report.
