History
Robby Findler 57deb86f7b don't invalidate the error ranges for online check syntax when there is no admin 
I believe that this can go wrong in the case that you edit a buffer and switch tabs
before drracket fully finishes responding to the edited buffer (due to a queue-callback
that postpones some of the response to editing the buffer) for online expansion.
At least, this is how I guess that the error below happened:

send: target is not an object: #f for method: get-view
