Thanks! That's really good to know. To summarize, I think the three clues we have so far are that this bug:

• Reproduces while performing a single tap to change the editable selection
• Does not require Switch Control to reproduce
• Reproduces with a hardware keyboard attached
  (though, it's unclear if it *only* reproduces when a hardware keyboard is attached)

I haven't been able to reproduce simply by tapping around inside contenteditable text with a hardware keyboard attached on iPad, so there's definitely more to this bug. In the meantime, do you have stats on which device models (i.e. iPad vs. iPhone) are experiencing this hang? If a disproportionate number of users are hitting this on iPad (despite iPhone users being far more common), I think it would be a strong indication that the hardware keyboard plays an important role in reproducing this.
