Thanks @KatieWoe, unfortunately this is something that has been around for a long time. It is a JAWS performance problem/bug and an issue for all sliders on the Web, not specific to PhET. I am pretty sure this is https://github.com/phetsims/qa/blob/master/documentation/accessibility-bugs.md#122-chrome-bugs.

Can you please see if this happens in the published sim too? If so I think that will confirm there is nothing new in the sim causing this and this can be closed.

It does look like it is in published.
