Fix IE focus problems in the robot tests Toolbar.html and !TooltipDialog.html.

Show/hide of popups was implemented via dynamic addition/deletion of DOM nodes to the document.   Those dynamic additions/deletions caused the current node to lose focus, or when the user tabs to a new field it gets focus momentarily but then focus jumps to <body>.

Best solution I could come up with was to pre-create the popup wrapper <div> and then not recycle wrapper <div> or <iframe> (although a possible optimization would be to recycle the iframe).

Fixes #10404, #11193, refs #11132, #10016, #10167 !strict.
