Frame tageting is broken again.

Frame tageting is broken again.

Hi. Behavior that has been working for 2 years is now not working. The submit success message is breaking the frame targeting.

Use Case:
1) Target a frame using the anchor link attribute TARGET. Like this:
2) Open this page and click this link: Matthew Trouts
  1. <a class="_Lnk" target="tskCal" href="http://creator.zoho.com/ensobase/david_bartels/Listings/record-edit/All_Listings/243881000033951289/&zc_SuccMsg=Finished" style="font-weight: bold;">Matthew Trouts</a>
3) The proper form loads in the Frame.
4) Click on the submit button on the form in the frame. All is good.
5) Go back and click the same link Matthew Trouts. Here is where the bug is.
     The same link will now open in a new window/tab of the browser.
