Cross site copy paste functionality keeps loading forever after pasting

[AF1QUE]

Prerequisites

• I have searched for similar issues in open and closed tickets and cannot find a duplicate.
• I have troubleshooted my issue, and it still exists against the latest stable version of Elementor.

Description

When I copy any section/element from another site and paste it into my Elementor editor, the copy/paste modal keeps loading forever. I can see the template was copied successfully in the background, but it doesn't close the modal automatically. This bug only occurs on the latest version of Elementor.

Steps to reproduce

1. Update Elementor to v3.21.4
2. Copy any container from your existing site or you may use https://skelementor.com/components/
3. Try to paste the copied code into your destination site

Expected behavior

After successfully pasting the template, the modal should automatically close itself.

Isolating the problem

• This bug happens when only the Elementor (and Elementor Pro) plugins are active.
• This bug happens with the Hello Elementor theme active.
• I can reproduce this bug consistently by following the steps I described above.

I have faced the same issue as well. It seems like a frustrating bug that needs to be addressed by the Elementor team!
