So um. Sorry, I'm sure every new person asks this. But do I have it right that if I open some toots in tabs (and they're not coincidentally on my "home server"), and, upon reading, want to interact with them, then the only way is to copy the URL, go back to my home server, and paste the URL into the search bar? I'm not missing anything?
Update: I discovered that if you *left-click* on a thing in the timeline, it opens a view of it that's still on the same server, so interaction works. It's only middle click to open a new tab that goes to the originating server. The internet has thoroughly trained me out of ever left clicking anything on a website with infinite scroll.
There is a github issue about it: https://github.com/mastodon/mastodon/issues/19652 and apparently the behavior has been changed as of Mastodon 4.0, which is presumably what @kha had in mind in their earlier reply to me.
