Assert fail #18439
<!-- Please describe your changes on the following line: -->
This PR addresses #18439 by removing an assert statement that forces a panic whenever `LoadBlocker` is dropped during a GC sweep and receives a `None` `SCRIPT_THREAD_ROOT` value from `mark_document_with_no_blocked_loads()`. Instead of panicking on the assert, we remove it and let the None value pass silently.

Remove an unnecessary synchronous full reflow.
We already reflow any nodes that are dirtied during any turn of the event loop. There is no reason to synchronously reflow the entire document, especially when we don't even modify it in this method.
