(I'm going through old bug reports that unfortunately weren't
resolved at the time.)

I'm not seeing quite what you're seeing here in Emacs 26.1 or 28.  I'm getting:

* foo...ttttt|
* bar...

And then after showing, I get:

* foo
some texttttttt
* bar
some text

So this works better than the described problem (no "bartt"), but it's
still somewhat confusing.

On the other hand, I'm not sure quite what it's supposed to do if you
type after the dots.
