Shannon Booth d1c0fa3245 LibWeb: Do not spin the event loop on processing iframe attributes ...

Partially reverting a3149c1ce9

Spinning the event loop was causing a crash on:

https://wpt.live/url/percent-encoding.window.html

As it was turning what is meant to be a synchronous operation into an
asynchronous one.

The sequence demonstrated by the reproducing test is as follows:
  * A src attribute is changed for the iframe
  * process_the_iframe_attributes entered with valid content navigable
  * Event loop is spun, allowing the queued iframe removal to execute
  * process_the_iframe_attributes continues with null content navigable
  * 💥

(cherry picked from commit 30377e6e3500049c5442fac9d242d3b795861116)
