Thanks @loganbraywork. Unfortunately I think this is a bug with JAWS and not the sim. JAWS will do this will all sliders on the web, not just the leg in this sim. I believe this is listed in https://phet-dev.colorado.edu/html/john-travoltage/1.6.0-preferences.6/phet/john-travoltage_en_phet.html, can you please confirm? If it is the same issue I think this can be closed.

I am pretty certain this is the known JAWS behavior problem. Good to know that it still exists but there is nothing for PhET to do about this. Closing.
