note this line only works on aura currently, but it needs to be fixed higher up.
WebModal dialogs are owned by a WebContents, and only the WebContents for the
active tab on Mac have an associated NSWindow. They all have an NSView, but
there's no FindBrowser* for that.

The fix is probably that TODO already at constrained_window_views.cc:154
"TODO(gbillock): Replace this with PopupManager calls". which I think will
remove the need for GetModalDialogHost() altogether. That TODO is probably made
a lot easier by MacViews, and so the circle is complete :)

But that's all for another day..
