2005202 - Assertion failure: PermissionAvailableInternal(prin, aType) when restoring an about:blank with content principal

Status: NEW

(Core :: Permission Manager, defect, P3)

Description

[Vincent Hilla [:vhilla]]

This is similar to bug 2004165, but unlike that one, this already failed before bug 543435 landed.

Steps to reproduce, on a debug build:

• Go to https://example.com
• In the console, do window.open("about:blank")
  • (requires user activation, i.e. click on the document beforehand or call this off of a click handler)
• Restart the browser and restore the about:blank tab
  • E.g. in another tab, go to about:profiles and click restart normally
• Go to the about:blank tab
  • Ensure you don't touch the restored example.com beforehand. You can close it before restart to be sure.

This fails MOZ_ASSERT(PermissionAvailableInternal(prin, aType))

I'll likely land a test in bug 2004165 that can be used for this crash too. If so, I'll annotate it with skip-if = debug for now.
