Provider resource API call is too slow on azure resource explorer UI

[mdv27]

I am trying to change settings of azure app service having EasyAuth enabled. While traversal, each expand action API call takes ~4 Minutes. From browser network tab I can see GET https://resources.azure.com/api/operations/providers/{id} is the call which takes this longer.
I think the site behavior can be improved upfront by caching response of this API call as its called with each expand action on UI. Also its very high response time for an API call in general.
Web app url: https://resources.azure.com
Azure service: app-service

I experience exactly the same.
I had several attempts on Chrome, (opted out of the last attempt after waiting 16 minutes).
Then I used Edge and it responded within a reasonable timespan.
It was also possible to access the providers within a reasonable timespan in chrome with a new incognito window, so seemingly it's a cache issue and most likely related to issue #347
