This will need careful review, and probably additional tests, to ensure that there are no regressions or changes in behavior.

We will need to run it through our headful test system as well, since headless sanity testing is not going to be sufficient here.

This isn't something I want to do quickly, so this will need to wait until after the jfx26 fork and we have sufficient time to test it.
