  @summary ANCESTOR_RESIZED is not sent while resizing a frame. Regression caused by 6500477.

/**

 *

 * summary:  After fixing the 6500477, the ANCESTOR_RESIZED event stoped

 *           firing while resizing a frame. This was a regression.

 *           The test checks whether the event starts dispatching as it

 *           was before fixing the 6500477.
