[tooltip] Trigger does not work when rendering disabled elements

# Bug report

## Current behavior

Tooltips do not appear when the trigger is wrapped around a disabled button

## Expected behavior

Tooltips should appear

It does not show because `mouseOnly` is true in FloatingUI's [useHover](https://floating-ui.com/docs/usehover#mouseonly) and disabled elements do not fire mouse events. Pointer events do still fire, and setting `mouseOnly` to false or undefined will allow the tooltip to show up (this could also be intentional for accessibility reasons, but [the behavior differs from Radix](https://codesandbox.io/p/sandbox/pedantic-curie-eojbiv?file=%2FApp.js%3A13%2C18))
