Hi,

is this known/excpected?

Same with Firefox 128.0.2 on desktop, Ubuntu Linux in my case.

I compared to other Firefox installations I have access to. Curiously, there it did work as expected:

• Firefox 115.11.0esr on Windows
• Firefox 102.6.0esr on the same Ubuntu Linux machine as the 128.0.2 above.

I couldn't check against a current Firefox version on Windows (can't install on the Windows machine; and PortableApps Firefox is currently broken...). So I am unable to narrow it down to either more current Firefox versions or something exclusive to Linux.
