Subject: [PATCH] Don't dispatch "pagerendered"-events on the *temporary*
 CSS-only zooming done when `drawingDelay` is used (PR 15812 follow-up)

We shouldn't dispatch a "pagerendered"-event when doing *temporary* CSS-only zooming, but simply wait until the actual rendering is done.
While I don't believe that this regression has caused any actual bugs, dispatching *duplicate* events is nonetheless inconsistent and should be fixed.
