Identify a document open (even if it is the same name)

[danyill]

Currently, I think in plugins we can't identify a new document has been opened even if is the same document (and especially if there have been no edits made).

My testing of a plugin so far suggests that even if edits have been made and I am using editCount with a @state decorator I don't get a re-render (although I may be erring in some fashion).

Filing this issue as requested by Christian.

The result is that it does not refresh the applicaiton.
