Does the bug happen if you start with --temp-basedir?:
Don't know, as saved sessions are not available with this option.
Description
Opening qutebrowser sesssion and afterwards quickly closing before all of the tabs have been loaded, kills of some tabs(probably those which hadn't been loaded at that time) and sometimes all the tabs. these tabs show a pid of 0.
How to reproduce
Open the browser with some tabs in default session or load some session and quickly close the browser using close button.
its worth noting that i have auto_save.session is enabled.

This happens due to #5359 combined with #2176.
