I would like to customize styling for recurring events in Calendar (115.11.1 on MacOS) without using extensions/add-ons. I enabled userChrome.css (`toolkit.legacyUserProfileCustomizations.stylesheets`) and the “has:” selector (`layout.css.has-selector.enabled`). In my userChrome.css, I added styles:
li:has([alt*="Recurring"]) { background-color:grey !important; padding:1rem !important; } li:has(*[alt*="Recurring"]) { background-color:yellow !important; padding:1rem !important; }
Unfortunately, this seems to have no effect upon restarting Thunderbird. However, when I open Developer Toolbox (`Tools > Developer Toolbox > Developer Toolbox > Inspector` tab) suddenly everything works and the stylesheets are applied, but only until Thunderbird is shut down. Weirdly, other custom styles in userChrome.css work ok.
Is this intended behavior or a bug?
