'transitionrun' event is delayed if a page has text selection, and the
transition detection logic in style.mjs didn't work in this case.

After this CL, we remove '$part-transitioning' part in
attributeChangedCallback. This works well because Blink doesn't compute
style for <std-switch> before calling attributeChangedCallback for
'on' attribute.
