The tests IrresponsiveScriptTest time out differently on all platforms:

Linux: testInfiniteLoopInScript hangs
macOS: testInfiniteLoopInScript hangs
Windows: testLongLoopInHandler fails (but testInfiniteLoopInScript passes)

The browsers like Chrome or Firefox do not interrupt an infinite JS loop.
So we can hold on to this fix for a while, but it should be fixed as this is a JavaFX behavior.
