Thanks, but it didn't quite work. It did however trigger a state where I can avoid the bug. Instead of the embedded html showing directly, I get a warning stating that it is disabled because of security. I can choose to disable the sandbox, and the application restarts, showing the html, crashing again. So I can just not disable the sandbox and avoid triggering the bug.
