Enable the feature flag created in T394704
Open Topic parser caching: T394291#10836697
AC:
- $wgWBRepoSettings['tmpMobileEditingUI'] is toggled on and thus MEX is the default view for mobile devices on beta wikidata (https://www.wikidata.beta.wmcloud.org/)
- Communication to community sent at the time of the release
- Make sure that previous parser cache entries for non mobile remain valid (=> parser cache keys don't change). Especially when tmpEnableMobileEditingUIBetaFeature is false, like on Wikidata.
Notes
- For the new mobile UI, the parser cache key should change probably by changing the wbMobile option
- We'll enable MEX as the default mobile view for everyone on beta wikidata
- This is not blocked or dependent on anything
