Summary

Firefox 147 supports the activeViewTransition property on both the Document and Element interfaces. See https://bugzilla.mozilla.org/show_bug.cgi?id=2001836.

This PR:

  • Updates the Document.activeViewTransition data point to add the support info for Firefox.
  • Adds a new data point for Element.activeViewTransition with the same data as the other one. (I documented activeViewTransition when Chrome supported it in version 142, but I forgot to add support data/docs for the Element version). — update: after doing some testing, it seems like Element.activeViewTransition isn't supported in Chrome or Firefox, so I've removed that data.
