Since `consumeAutoHidingEvents` property value is asserted in the test, I'm suspecting that it is getting asserted before the mouse moves away from the slider and `consumeAutoHidingEvents` property value is reset to original value.
Since the test is not failing consistently for me in Ubuntu, I believe possibility of product issue is less. Hence  added a latch and small delay to make sure that the property value is asserted only after the mouse is moved.
@kevinrushforth  could you please check this fix.
I have ran the test in Ubuntu 22.04 VM multiple times and test didn't fail.
