V4 e-paragraph (also components): a link added in the text is saved with unescaped ", making _elementor_data invalid JSON and blanking the page

Description

On Elementor and Elementor Pro 4.3.0-beta3 (Editor V4), adding a link to part of the text in a paragraph and clicking Update stores the paragraph as "paragraph":{"$$type":"escaped-html","value":"Call 407-777-1790 or ..."}. The quotes inside the value have no backslash, so the whole _elementor_data meta is invalid JSON (Expecting ',' delimiter). The page then renders with no sections, and later saves keep the corruption. It happened on every save that contained such a link, at least 6 times, on the Home page. It also happened with a link set in a component text override, and in a Custom HTML widget containing an iframe with double-quoted attributes. I confirmed it by reading the post meta and the revisions through the REST API: the last revision before the link is valid, and the one right after is not.

Steps to reproduce

Create a page in the Editor V4 and add an e-paragraph widget with some text. Select part of the text and add a link with the toolbar (for example tel: or a URL). Click Update. Open the front end, or read _elementor_data (post meta or revisions).

Expected behavior

The link is stored with escaped quotes, the data stays valid JSON, and the page keeps rendering.

Also to state: I have not tested on a clean install with only Elementor, Elementor Pro and Hello active, and the site runs a beta build.
