Uncaught ReferenceError: newTop is not defined ON CONSOLE

Using CRM v7.13. PHP 7.4. Tried QR&R. Permissions are correct.

I am getting a console error when I am trying to save or edit any dashlet on home screen. Not able to edit or add dashlets.

Anyone know what’s root cause? Any solution?

MySugar.js?v=xWx0eIxvQx-xSuYs2iwxMg:49 Uncaught ReferenceError: newTop is not defined
    at Object.fillInConfigureDiv (MySugar.js?v=6WY0eIRvQx-xSuYs2iwxMg:49:481)
    at Object.handleTransactionResponse (sugar_grp1_yui.js?v=6WY0eIRvQx-xSuYs2iwxMg:31:4422)
    at sugar_grp1_yui.js?v=6WY0eIRvQx-xSuYs2iwxMg:31:3935

If we click on edit(pencil) icon of dashlet on home page, we are getting the below pop-up.

seems to be a bug. Not sure. Did you figure this out ?

No, I am not able to figure it out and no one has solution I guess.

It was fixed in 8.5.1 . Just upgraded and its resolved

What is solution? Could you please share code with me?
