Why would m_listBox's parent not be null?


R- for the typo

Fix type

Heh, typo in "Fix typo". Nice.

> Why would m_listBox's parent not be null?

I was surprised too, but the branch for regular popups (PopupContainer::showPopup()) checks this too. So I figured it's safer to check this here as well.

Landed as http://trac.webkit.org/changeset/51102

I'm working off a tree from yesterday and I just wound up having to make this change to fix http://crbug.com/27723.  Then I went to merge my work into WebKit so I could get it landed here and I got a merge conflict because you already hit this.

Excellent!

(Yeah, this is the correct fix.)
