[Shadow root][Iframe] The text should be selectable inside <FocusLock/>

[JuliaMV]

The content of FocusLock that opened inside of shadow root or iframe is not available for user-selection.

How to reproduce:

1. Open the demo sandbox (with iframe) https://codesandbox.io/p/devbox/focus-lock-with-modal-forked-vmr9sl?workspaceId=ws_BCJDEdyBHvVP9ekjRYa7KV
2. Click "Open modal" button
3. Try select some text to copy it

Hi JuliaMV,

I have a similar issue, but we are not using iframe; we are using shadow DOM and web components. However, I can't reproduce it in a code sandbox environment.

I cannot access the URL you provided. Could you share that again to see if I can reproduce my issue too?

"DevBox is not available" 😿

In any case problem seems to be related to #335 and I reckon the problem is this line - https://github.com/theKashey/react-focus-lock/blob/master/src/Trap.js#L138
