Should be:
Per discussion on Telegram, the fix merged in https://github.com/musescore/MuseScore/pull/3902 is incompatible with the simplified "skyline" algorithm. A new approach is needed.
Tried to give better (specific) title
My suggestion for a fix would be a less "greedy algorithm. Currently, we lay out text elements left to right, and if an element intersects the current skyline, it is moved up. What we could consider instead is to "pass" on that element, go on to the next, and if the next can be placed without needing a bump up, then go back to the previous element and autoplace it. This would yield the desired result Isaac's example above - first placing "testing first", then passing on "testing second", then placing "testing third", then going back and placing "testing second".
Complicating this is the fact that different types of text are placed at different times, and this itself is kind of an important aspect (eg, tempo should always be above staff text). But this approach should work well within each type.
