I’ve been seeing more of this bizarre type of request whenever I look at the DevTools Network, with a strange request URL from https://perchance/cdn-cgi/rum. But whenever it stalls or not, it sometimes still lets me save the generator properly, and in some cases, it halts the saving and loading process almost indefinitely. But any good explanation is appreciated!
That is the details of the “pending” rum request:
“Real User Monitoring”?

Ahh, that’s how I knew the abbreviation already. But I still wonder how the request could halt the saving process (sort of, because sometimes the save still succeeds anyways, this could be seen by the revisions adding an entry to the latest save date of the generator).
