[tooltip] Using Tooltip.Trigger's render prop with a forwardRef component doesn't trigger the tooltip

[iansjk]

Bug report

For <Tooltip.Trigger render={...}> I would expect to be able to use a component for the render prop, but it seems that this doesn't work.

The specific case I observed was for <label>.

Current behavior

• Using <Tooltip.Trigger render={<label>...</label>}> triggers the tooltip
• Using <Tooltip.Trigger render={SomeOtherComponent}> (where SomeOtherComponent forwards a label ref) doesn't trigger the tooltip

Expected behavior

Both methods trigger the tooltip

Tested the same thing with popover and it works fine: https://codesandbox.io/p/sandbox/friendly-night-forked-3fwdxx

The props aren't being forwarded to the underlying Checkbox label element:

export const Checkbox = forwardRef<HTMLLabelElement>((props, ref) => (
  <label ref={ref}> // <-- missing {...props}
    <input type="checkbox" />
    hover me
  </label>
));

It may happen to work sometimes since the ref gets assigned native event listeners but React props also get assigned and are necessary to ensure all functionality works as expected
