Because frequent resizing causes iframes to be destroyed before they are loaded, the onload of the iframe is not executed, which causes a promise to remain in a pending state and block the queue. See the section I modified for details. |

Make sure the promise doesn't get stuck in pending, this avoids queue blocking.

Ensure that the previous instance of the current page is destroyed to prevent promise blocking.
