Search list opens in the wrong window when TagBar is enabled

[goglecm]

When used with TagBar, https://github.com/majutsushi/tagbar:

You do a search. The search list pops up in a new horizontal bottom split. You then close it :cclose and when you open it again with :copen it opens as a bottom horizontal split of the TagBar split as opposed to opening as a bottom horizontal split of the original split.
