Prior to the introduction of directives it was possible to open any file in a library and have the entire library opened. That should still be true, so this should work. If someone changed things to allow opening only library files then this is illustrates a bug that is very confusing (see the error message).

Removed Priority-Medium label.

Rev 603. - opening ClockNumber.dart works fine, don't see any errors. The logic for opening a file and looking for library has not changed.

Cannot reproduce

Appears to be working in rev 604. Apparently the problem had nothing to do with the logic for opening a file.

Added Verified label.
