Actual:
Label for "Edit tab" unexpectedly displays raw wikitext.
Other notes:
Probably specfic to User/File namespace.
Probably not fixable, in so far that it's working as expected with this kind of parser syntax not allowed in these cross-platform interface messages. Perhaps we need to make sure the message is documented as being limited to the safe subset of message syntax (if not already) and fix, or help community to fix, their local override to comply.
Might be a recent regression, in which case perhaps it worked in a different way before, maybe VE had its own version of this message.
