Changing parse context doesn't update code model

I have files that are used in multiple projects so I have available the parse context dropdown for this, the problem is that if I change this parse context nothing happens, I need to insert eg. empty space at the end of the line and save and then the code model is updated (save isn't really needed, it's enough to change the file to update code model).

I think the best will be to do the screencast of this problem, where everything will be clearly visible.
