test failures due to async focus() execution (IE9+)

[haysmark]

In IE9 and 10 the robot TabContainer_a11y has some test issues with focus. A lot of tests use the pattern 1) focus, 2) set up focus handler, 3) do robot action to focus something else. But the problem in IE is that the focus call does not get invoked until after the thread is released, so the test fails because the handler detects the focus going to the first focused element.

Fix test issues in TabContainer_a11y in IE9 and IE10. Fixes #16926.

On IE9+ clicking a Button (with the mouse) to open a Dialog and then closing the Dialog doesn't refocus the Button, due to the async nature of the focus event. But I don't think we should be guaranteeing refocus except when the Dialog was opened via keyboard (tabbing to the Button and then pressing ENTER/SPACE). So changing the mouse test to not check for Dialog refocus. Refs #16926.

Use IE's native focusin/focusout support for IE9+ too, avoiding asynchronous focus notification, fixes #16968, #16970, and refs #16926, #16972 !strict.
