STR

• Open the debugger
• Reload the page
• Collapse the source tree item (Note: source tree item is broken - this should be fixed by Bug 1982001)
• Click the source tree item to open the source

Actual Result

Error loading this URI: sourceContents failed: Error: Protocol error (Error): Could not load the source for <script>1</script>.

Expected Result

The source content x -> <script>1</script> should be displayed.

We most likely already have a bug to avoid leaking the JS exception in the debugger UI, so this bug should really be focused on trying to properly handle such a source.

Note that we have Bug 1834721 to have dedicated UI when we can't open a source instead of putting the error message in the source editor
