Made respondsToPointerEvents() more resilient to execution off-EDT by…

… only calling isScrollable() if it is running on the EDT. This is because isScrollable may trigger some mutations from the UI while it determines if the component is scrollable. This likely fixes the issue that #3323 is meant to address.
