Cannot use CMD+V to paste inside a shadow DOM input element (After-Effects)

[GoodBoyNinja]

With the following code I am creating two inputs:

// regular input
let input = document.createElement('input');
input.placeholder = 'Regular'
input.type = 'text';
document.body.appendChild(input);


// shadow input
class CustomInput extends HTMLElement {
    constructor() {
        super();
        this.attachShadow({ mode: 'open' });

        let input = document.createElement('input');
        input.placeholder = 'Shadow'
        input.type = 'text';
        this.shadowRoot.appendChild(input);
    }
}

customElements.define('custom-input', CustomInput);
document.body.appendChild(new CustomInput())

The first one is a regular input,
while the second one is a custom element using Web Components which contains an input in its shadow DOM.

In After-Effects, using cmd+v to paste content only works for the first one.
With the second input, After-Effects steals focus to one of its panels.

@GoodBoyNinja You might also want to mention this in: https://community.adobe.com/t5/after-effects/ct-p/ct-after-effects?page=1&sort=latest_replies&lang=all&tabid=all&topics=label-scripting or https://community.adobe.com/t5/after-effects/ct-p/ct-after-effects?page=1&sort=latest_replies&lang=all&tabid=all&topics=label-SDK

... unless this affects more than one application and is definitely a CEP issue of some sort, and not say, an After Effects issue.

Thanks Erin! Seems like the same things happens in Illustrator.
