Damus had similar bug already some time ago. I sure #[4]β will fix this soon π€
Seems like even nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 canβt deny how good nostr:npub1plstrz6dhu8q4fq0e4rjpxe2fxe5x87y2w6xpm70gh9qh5tt66kqkgkx8j has become as of late π

Back then they had it when you tried clicking on any tags, that it directed you to the latest installed npub supporting clients π€
Easy fix right now seems to be just to make it into a non-directive tag and just a regular editable text like the rest of the note.
We remembered with Will about that bug at BTCPrague. We probably jinxed it.π

We just need to make sure the internal link is damus:nostr: instead of nostr:
