Wrong use of aria-hidden

[mp-horm]

Describe the bug
Carousel items are marked as aria-hidden=true when not visible. Aria-hidden should only be applied to non-interactive elements.
https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-hidden
The attribute causes WCAG errors when using focusable elements (buttons, inputs, links) in carousel items.

To Reproduce
Steps to reproduce the behavior:

1. Render a carousel with two items, one of them using a focusable element (ie a button)
2. Click on the non-button item
3. Copy page html to https://validator.w3.org/#validate_by_input
4. See error related to
   https://accessibilityinsights.io/info-examples/web/aria-hidden-focus/

Expected behavior
No accessibility errors

I second this. During my migration to vue 3, its compatibility mode keeps logging the aria-hidden property's false-value.

I'm also noting that the carousel has a tabindex="0" so it's focusable, but then it does nothing with the focus (like using arrow keys to slide prev and next)
