In 5d27679 I've attempted to trigger the same flow as when metaboxes are triggered. This allows for the logic that @chriszarate suggested above to happen

Noting that with the latest commit, the PR is ready for review once more. Flagging that the the room whose update exceeds the set size will be the one that'll be unregistered, thanks to the re-working of the way update sizes are detected. It's within the doc sync function. So it is possible that there would be updates going in the background despite the post-locked modal showing up, as rooms like |

What?
Set the limit for the maximum size of an RTC update to 1MB for the default provider.
Closes #75315.
Why?
As the site editor's performance tests were failing, we disabled them in #76223, which allowed those tests to pass. As far as we can tell, large-post.html causes the updates being sent to the HTTP Polling provider to overwhelm it. They also exceed the limit set in place in WordPress/wordpress-develop#11068. This is with just 2 collaborators in total, and the exact issue is a critical error encountered when trying to allocate memory for the request.
This makes it clear that the number of collaborators alone can't be what dictates the limits of a provider.
How?
enteredAttimestamp for each collaborator.Testing Instructions
