Awesome!

I tried typing English (Canada) in the search field here, but it blows up the page :-) As soon as I hit ( there was an uncaught error about "unterminated parenthetical". Same thing if I type ( in the timezone search.

Maybe this should be Millisecond*s*?

Uhhh opps, my bad ^^ Looks like we didn't escape the search text (seems to happen everywhere else too). It should be fixed now :D

Yep just did^^

In the latest commit, I added some css fixes for elements (i.e. those that were upgraded to PF5) to be compatible with dark theme. I think we can fix the rest while upgrading other remaining views :D
