It's possible for the DTD Editor service to send a ActiveLocationChanged event with a null textDocument when a 'synthetic' file is selected (e.g., IDE settings, the widget previewer, etc.). The previewer should not react to these events and should continue rendering the last set of filtered previews from a valid source file.

Code Review

This pull request correctly addresses an issue where the widget previewer would update incorrectly when a non-source file is selected. The change ensures that the preview set is not updated if the selected file from the DTD Editor service is null, effectively preserving the last valid state. The implementation refactors _handleSelectedSourceFileChanged to _updateFilteredPreviewSet and adds the necessary logic to handle null textDocument events. The accompanying test changes properly validate this new behavior. My review includes suggestions to simplify the listener registration logic for improved readability and maintainability, and to tighten the scope of a local variable.
