Follow-up to fefb76eebc. Prior to that
change, the condition for this looked like this:
// … if on a ?veaction=edit/editsource page
(
isViewPage &&
uri.query.veaction in editModes &&
(
uri.query.veaction === 'editsource' ||
init.isVisualAvailable
)
)
In the refactor, the `uri.query.veaction === 'editsource'` check was
lost.
Since that code is pretty messy (probably predating the source editor
and hastily adjusted), instead change the check for `isVisualAvailable`
to just `isAvailable`. If the requested mode turns out to not be
available later, the editor will not load.
