Popup message on close of pick or MVG applet in OpenUI

Dear Team,

We are working on siebel open UI IP15 ps 9.

When we click on 'X' (close button) of any pickapplet or MVG applet, it gives popup error:

"Click OK to discard unsaved data and close all popups"

(There is already a defect 'Doc ID 2120165.1' for the same.)

We dont want this popup message to appear on click of 'X'(close button)

However, we have fixed this by modifying vanilla object which is not a best practice but can be considered till we fix this through custom PR.

I have created custom PR.js and associated with FRAMEWORK and DEFAULT FORM APPLET.
