Non-native scrollbar setting not working in Firefox 90

I'm using Firefox 90 on Linux (Fedora 33) and MATE Desktop. Before I upgraded to Firefox 90, I set widget.non-native-theme.enabled to false to revert the scrollbar appearance to the system theme, as per this question: Scrollbar appearance changed after Firefox upgrade. It worked on Firefox 89, but as soon as I upgraded to Firefox 90, the scrollbars went back to the non-native appearance.

After the upgrade, the widget.non-native-theme.enabled is still set to false, but apparently ignored. However, I noticed that the other widget.non-native-theme.gtk.scrollbar.* settings that allow scrollbar appearance customization inside Firefox are ignored as well. If I set widget.non-native-theme.enabled back to true, then the other scrollbar settings work as expected. This tells me that widget.non-native-theme.enabled does work, but the system scrollbar theme is not picked up as expected. This looks like a bug to me.

Are you using a GTK 3 theme in Linux as older GTK 2 themes might not work properly ?

The system theme applies to both GTK 2 and GTK 3 applications. Scrollbars look normal in all other GTK 3 applications. For what is worth, the same theme worked just fine in Firefox 89.
