Hovering Button with Tooltip in a PreviewTrigger Popover closes the Popover

### Provide a general summary of the issue here

When a `Button` inside the `PreviewTrigger`'s `Popover` has a `Tooltip`, hovering the `Button` closes the `Popover` immediately.

### 🤔 Expected Behavior?

The `Tooltip` should display per usual and the `PreviewTrigger`'s `Popover` should remain open.

### 😯 Current Behavior

The `PreviewTrigger` `Popover` closes when the user's pointer hovers over the `Button` that is used as a `Tooltip` trigger.

### 💁 Possible Solution

_No response_

### 🔦 Context

In a `Popover` component that displays user's locale and UTC date strings, I'd like to include a gear icon `Button` that links to timezone settings; to remain accessible the icon button needs a RAC `Tooltip` i.e. "Timezone settings".

Start by running the linked StackBlitz reproduction in src/App.tsx and inspect how the PreviewTrigger Popover, Button, and Tooltip interact on hover. Confirm that the Tooltip displays normally while the Popover stays open, including for the timezone-settings icon-button scenario described in the issue.
