Change subject: Make LinkCache fail more gracefully when given undefined
......................................................................
Make LinkCache fail more gracefully when given undefined
If you tried to do styleElement( undefined, $element ), you'd
get an exception in the mw.Title constructor from a setTimeout.
That's not very nice, and there's no point sending non-strings
through the queue and other data structures in LinkCache, so
instead just make get() return a rejected promise when given
non-string values.
