Leaving pega iframe in IE11 causes buttons to be inactive
User has an IAC implementation of their Pega application with a custom code to handle clearing of pega cookies when the end user clicks away from IAC loaded harness. When users click away, they observed a pop up giving an option of "Leave this page" or "Stay on this page". And when users choose to stay on the page, the action buttons are disabled and there was no network call done upon clicking them. User expects the IAC loaded harness to remain fully functional upon staying on the page.
no errors displayed
Steps to Reproduce
1. On any of the Change Fund pages, if we choose to navigate back to FNC, there will be a pop-up asking the user to either ‘Leave this page’ or ‘Stay on this page’.
2. If we select ‘Stay on this page’, the action buttons are all disabled.
The root cause of this problem is defect/misconfiguration in the PRPC operating environment.
To resolve this, and prevent popup, simply return nothing in the logoff function called by onbeforeunload listener.
