In T264355 we integrated WVUI into Vector, but it depends on the existence of WVUI in core. This in itself is blocked on the security review in T257579.
Acceptance criteria
- Security gives the all clear on merging WVUI into core. Web team has taken care of any outcomes of the security review
- The https://gerrit.wikimedia.org/r/c/mediawiki/core/+/641052 patch is merged
- Vector is updated to remove the conditional registration of the module that depends on WVUI (https://gerrit.wikimedia.org/g/mediawiki/skins/Vector/+/f6e790b11864532ce2ae2839fd588e7e99c9ef8f/includes/Hooks.php#352). The definition should be moved to skin.json
- Core is using the very latest commit from WVUI
