Error when you pick an image in media controller (custom widget)

Prerequisites

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

Description

Hi, I've created a custom Elementor widget and, in a repeater, I added a media controller input (only for images). When I select an image file from the media library and I confirm, it doesn't get added. In the console I get the highlighted error. I think that in editor.js, in that line of code, it should be "default_value" instead of "default".

Steps to reproduce

Create a custom Elementor widget wih a repeater input and for every item of the repeater add a media controller input field for images.
Add an instance of that custom widget somewhere in a website (eg: in a page).
In an item of the repeater, open the media library to select an image for that input and confirm the choice.

Expected behavior

The image should be set as value of the image field.

Isolating the problem

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