This crashes on JavaFX 21 GA (WebKit 615.1) and 22 GA (WebKit 616.1) as well. So it seems likely that some recent change in the web site has provoked this. All of my tests were done with JDK 21.0.2, and while I suspect the version of JDK doesn't matter, I will repeat the test with an earlier JDK (e.g., 21 or 20.0.2) just to rule that out. UPDATE: I tested with two earlier JDKs (JDK 19.0.2 and 17.0.1) and the crash is still happening. So it does seem that some recent change in the web site content is now provoking this bug.
