JavaFX-Bugs on GraalVM 19.3 (Java 11)

My guess is that these are GraalVM bugs rather than JavaFX bugs, but 
without debugging them it's hard to know for sure.

Johan has spent a fair bit of time looking into running JavaFX on 
GraalVM, so might have some additional insights.

As for bug tracking, I don't have a problem with using the javafx 
component in JBS as long as we use a consistent label to indicate bugs 
that are specific to Graal so we can filter on that label. I might 
suggest "javafx-graal" but am open to others (I don't want to just use 
"graal" since the Graal team already use that as well as a couple other 
labels prefixed with "graal-").
