Background color button issue

[Rutorai]

Hello,

The queryCommandValue doesn't work with firefox (at least version 75.0 (64-bit) on linux). It always returns 'transparent'. So button color is not updated according to the backgroung color of the selected text.

It seems to be a issue with firefox for a long time.

Regards.

I see. The simplest way is probably just to ignore the transparent value in the function that detects this, that way it defaults to white at least.

I think it's not really bad to let the code as is. Finally, it works. But if one day firefox fix the bug ... or try another solution : with getSelection and css style. I found some workaround like that.
