Question about deadlock issue

If you have additional information that is relevant to reproducing the 
bug or helpful in identifying a possible fix, you can send it to this 
alias and either I or another OpenJFX Author, Committer, or Reviewer can 
add it to the bug report. I have updated the bug report with your note 
about where you found the situation reproducible.

Since the bug is easily reproducible with no known workaround, I set the 
target fix version to JavaFX 16, but there are no guarantees. If you or 
another developer want to take a stab at contributing a fix, that would 
make it more likely to be fixed sooner.
