IntelliJ not highlighting some dartdoc links, even though it knows what they should be.

Steps to Reproduce

I added a "See also" item to the dartdoc for the Paint object in the flutter engine, and the existing dartdoc had the text [StrokeJoin.miter] in it, and it was highlighted and linked, but when I added the same link in my new text, it wasn't highlighted and linked.

This seems like a bug: the same context can't find the link that it clearly knows about somewhere. I tried copy/pasting the one that works and pasting it where the new one is (to make sure I wasn't somehow typing something different), and it still didn't link.

@scheglov, More information on this, since it's still happening with the latest plugin. It appears to be something to do with bullet lists in Markdown. If I type this:

///  * [ReadingOrderTraversalPolicy], a policy that describes the order as the
///    natural "reading order" for the current [Directionality].

Then the Directionality is not highlighted.

But if I type this (minor indent difference), it is:

///  * [ReadingOrderTraversalPolicy], a policy that describes the order as the
///  natural "reading order" for the current [Directionality].

This is probably just a misbehaving RegEx, if I had to guess.
