Will find as soon as possible

Additional notes*

• Bug is reproducible only when copy/paste the link into the address bar. It is not reproducibe if user is typing the link

Blue star should be displayed next to reddit.com/r/usa, as it is displayed for youtube suggestion

Hmm, it looks like the urlbar is suggesting "https://www.reddit.com/r/usa" but the bookmarked url is "https://www.reddit.com/r/usa/" (note the additional final trailing slash).
Searching "usa/" returns the expected bookmarked url.
CTRL+D happens before the site redirects to the final version with the trailing slash, so it's bookmarking the url without slash.
This is quite unfortunate, the two urls should be somehow coalesced.

I can't reproduce the issue in Firefox Nightly 120.

It's likely that Reddit has updated their url rewriter rules so it doesn't apply anymore to them, but it may be valid for other sites. We should better handle the trailing slash and bookmarks.
