Control+W does not work after closing about:preferences

[luixxiul]

Describe the issue you encountered: Control+W does not work after closing about:preferences. This is a follow-up to #8974

1. Open about:preferences#tabs
2. Change "When closing an active tab" setting to Select the last viewed tab
3. Open a new tab
4. Visit https://github.com on the tab
5. Click 'Features' on the menu
6. Click Go back button two times with the middle mouse button on the navigation bar
7. Select the last tab
8. Control + W
9. Repeat ^ until about:preferences#tabs is closed

Actual result: A blank github.com tab is left, which cannot be closed with Control + W

Expected result: the tab should be rendered and be able to be closed with the shortcut keys.

By opening a new tab, the blank tab gets rendered fine.

@srirambv & @luixxiul can you repro on 0.17.x?

[luixxiul]

no it seems the issue has been fixed. it selects correctly the last viewed tab, which is not the tab opened first with the middle mouse button.

I'm wondering which PR has fixed the issue - @bsclifton do you have an idea?
