Strange behavior/disfunction on Bluesky

[ylemty]

Website: bsky.app

Bug: When a user has a country code in their username, the extension fails to change it in specific cases. The failure occurs in the username section of posts, as well as in the search's "People" tab.

Extension seems to work otherwise, including in the actual content of posts, and even in the username section at the top of user bios. One notable exception is Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿 which often produces black flags everywhere except for post content. (The screenshot below is actually the only time I had the Scottish flag appear outside of post content - very strange.)

Reproduction:

1. Navigate to Bluesky and search for a country code in the top-right search bar. (You don't need to be signed in to access public posts and profiles.)
2. Switch to the "People" tab. Assuming you search for a common flag (like 🇮🇪 or 🏴󠁧󠁢󠁳󠁣󠁴󠁿) you should see at least a few examples without having to scroll very far.
3. Visit their profile and view their bio and their posts.

Screenshots for an example:

Chromium version 127.0.6504.0 Windows 11

Not sure if this is a limitation or a bug, but I figured I'd submit it just in case.
