What were you doing?

Generating a project report that takes a long time

After closing the window, the report was still running in the pyreports container.

What should've happened?

If the tab that requested the report is closed, the report generation should be canceled.

No response

Additional context

This would be pretty easy with a task runner, but we will probably have to implement this manually.
