 The fix from #42530 (specifically [changeset:"42184"]) doesn't seem to
 work properly, and it behaves inconsistently across browsers. To
 reproduce:

 - Uncheck "Enable full-height editor and distraction-free functionality."
 in the Screen options
 - using Chrome, edit a long post starting in the "Visual mode"
 - select a word that occurs at about the middle of the post content:

 - switch to "Text mode": no scrolling happens and the selected word stays
 out of view:

 - switch back to "Visual mode"
 - the selected word is almost completely hidden at the top of the content
 visible area:

 Using Firefox instead, it behaves a bit better: at least the selected word
 is visible when switching from VIsual to text:
