For improved perceived performance, load MW chrome and RC filters, then load data
Closed, DeclinedPublic

Description

Some users have long wait times (4-5 seconds, or longer) for the initial Watchlist page to load. We can speed things up by making the initial request to Special:Watchlist return the MW chrome and RC filters app, the app can then make an API call to load data.

This approach would also help with the initial load of Special:RecentChanges.
