Editing issue: "draft being edited in another window"

[LutherBlisset]

Anybody else seeing this?

Happened a while ago on some posts I was composing, went away, now is back and is bloody annoying.

Just pops up while typing, eating the current word I am typing every time.

And no, I checked, I don’t have other browser windows / tabs open, across all browsers.

FTR: did not pop up during typing this. But at the last post. In basically every sentence I wrote about five times or more.

I have that, too. Sometimes that happens when I start a post on mobile and then want to pick it up on my desktop, but it also happens just randomly when there is definitely no second tab anywhere else. Annoying.
