Randomly, manifest editor can be opened only once #1963
Description
I just saw that on 4.38 latest SDK build, it must be a regression, probably even before 4.37.
Opening plugin.xml (or MANIFEST.MF) editor works only once.
First, on closing the editor this error below reported and later on opening same plugin.xml the editor is corrupted.
The problem is, I don't know how to reproduce, just open/close for any bundle seem to work, but if once the assertion failed: error is reported, it fails from this point for every bundle.
First time editor opens, but reports error on close

I believe (not sure) the code in org.eclipse.pde.internal.ui.editor.PDEFormEditor.dispose() does wrong way of dispose and calls the super.dispose() before disconnecting from document.
