Damn. I never knew that way to search things. I used to do « Share / Search on this page » which was already obnoxious, which has now become « … » / « Share » / « Search on this page ».
Either I’m dumb or there is a discoverability problem with all these features. Probably a bit of both.
If you go to settings > apps > safari, and scroll to the “tabs” secttion, then turn off “compact” you get rid of the “…” button and go back to what it used to look like before.
Which is why i didn’t notice the change, as i had already set this setting to put the url back at the top an update or two ago.
And yes, definitely discoverability issues.
