Do not open editor when .bpmn file can't be loaded

When I want to edit a .bpmn file that can't be loaded by the editor the extension opens an editor with only start node.
the editor shows an error dialog. See screenshots.

I would expect chrome-extension to not show any editor and go back to text view. Maybe notify user about this using alert window. I am able o edit and propose a file change so this is not a safe approach and could lead to confusion.

Happens on all channels.

Issue is located on kogito-bpmn editor side, tooling should be ok.

Acceptance criteria
User is notified via alert windows that shown diagram is not the actual one.
A text view is shown to user when he tries to edit a diagram that can be loaded.
