Modal: When using `isBackgroundClickDisabled`, nothing in the modal is focusable

[silvalaura]

Describe the bug If isBackgroundClickDisabled is true, nothing in the modal is focusable by mouse or clickable. Text is also not selectable.

To Reproduce Steps to reproduce the behavior:

1. Go to https://codesandbox.io/p/sandbox/s2hcml
2. Click on Show Modal
3. Try to click on any of the interactive elements, or select the text

Expected behavior

• The prop isBackgroundClickDisabled should not affect the ability to click on elements within a modal

Notes

• Notice how in the example, the bug only happens on the first modal, not the nested one
• The latest change in modal related to this was to support the background color with nested modals, so that should still function when this is fixed

Looks good!
