I have tested your issue on latest FF Beta 69.0b10 and latest Nightly build 70.0a1 (2019-08-04) and could not reproduce it.

Can you please try to reproduce your issue in safe-mode ( or
in a newly created profile (, to make sure that your issue is not related to the extensions installed or user data made on current profile and report back the results?

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.

Thanks for the report.
