Don't skip the resize if newWidth or newHeight is < 1 (#12002)

With full screen panel mode, the width and height can be updated to 0
(because the panel is hidden).  If _size isn’t updated, the second time
through it’ll skip the resize because of the if (newWidth ===
this._size[0] && newHeight === this._size[1])

Another option to fix this is to get rid of that check, and continue to
do the resize when the _size values are equal.  I felt this one was
slightly better, but could go either way.
