is this necessary? This assumes that the last tab is one of the newly opened
tabs. It also didn't appear necessary before.

Right, I fixed it to select the last tab inserted. I did this, because I want to
keep it consistent with ToolbarController when we do the same drag/drop
operation. Here we are inserting tabs in reverse order to preserve the order of
bookmarks. Previously we don't need it as we insert only on item.
