SS35: Enable settings for the flag if flag is enabled

Kam like i wrote i have little experience with that. never used flags, i only started with chrome://flags/#extensions-toolbar-menu since google added the extension button (so maybe 05.2020). today and yesterday i used it for edge just to test pip mode and tab groups** before sending suggestions.

i personally don't need it, for me is enough a better quick access, but this doesn't mean the suggestion is bad or other. it all depends from how you use the browser. i generally don't use flags. 

** i'm sure tab groups where visible directly before i manually installed all new edge browsers yesterday. or maybe i just make confusions with chrome and other browsers. 

for me is much important to not change for example chrome://flags/#extensions-toolbar-menu on all mac users and macs, like i'm doing until now (i maybe did it 150x), or that i need to reactivate it once the browser has a new version.  i wish that if i change on mac user 1 a flag, edge keeps such setting for mac user 2-100 on the same mac too.
