Comment (by afercia):

 First, very rough, pass for @adamsilverstein idea. Still experimental.
 Was thinking this sort of injected "focus placeholder" element can be used
 to dispatch a confirmation message (optional). Just passing a "Notice
 dismissed." string to be used as the placeholder content: when focus is
 moved to the placeholder, the message will be read out by screen readers.
 Without a message, screen readers may read out "blank", probably not a big
 deal and maybe someway appropriate. On blur, the placeholder should be
 removed.

 Many things to check, first of all if jQuery `insertBefore()` is the right
 thing to use,
 [https://github.com/jquery/jquery/blob/1.11.3/src/manipulation.js#L492
 checking also what it does internally]. Initially I thought it could lose
 the reference node, since we're deleting it but seems to work in latest
 Chrome, Firefox and also IE 8.

 Temporary styling just to make things visible for debugging. All this
 should be hidden with `screen-reader-text` of course.
 Would appreciate any help, thoughts, feedback and testing :)
