Bugzilla

STR:

1. Open Nightly with a fresh profile
2. Go to about:preferences#privacy
3. Check "Delete cookies and site data when Firefox is closed"

Expected:
In the "History" section on the same `about:preferences` page the dropdown is switched to "Use custom settings for history". The "Clear history when Nightly closes" checkbox is checked.
The settings modal to the right of the checkbox shows "Cookies and site data", Temporary cached files and pages" selected. The items "history" and "site settings" are *not* checked.
History is not cleared on shutdown.

Actual: 
The settings modal to the right of the checkbox shows "Cookies and site data", Temporary cached files and pages" selected. The item "history" is *also checked*.
History is cleared on shutdown.

[Tracking Requested - why for this release]:
Data loss bug, users that only want to clear site data will have their entire history cleared on shutdown too.
