Nested Popover closes PreviewTrigger when hovered

### Provide a general summary of the issue here

I am trying to use a `Select` (uses a `Popover`) inside a `PreviewTrigger`'s `Popover`. The nested `Popover` opens as expected, but when moving the pointer into it, the `PreviewTrigger` popover closes because the nested popover is rendered outside the boundary of the preview popover.

### 🤔 Expected Behavior?

The `PreviewTrigger` popover should remain open while hovering or interacting with a nested `Popover` that was triggered from within the preview content.

### 😯 Current Behavior

The nested `Popover` opens, but when moving the pointer from the `PreviewTrigger` popover into the nested popover, the preview popover closes.

Since the nested popover is rendered outside the boundary of the `PreviewTrigger` popover, moving the pointer into it is treated as leaving the preview area. This causes the preview popover to close and prevents interaction with the nested popover.

Start with src/App.tsx in the linked StackBlitz reproduction and trace the PreviewTrigger and nested Popover interaction. Reproduce the issue in Chrome, then inspect the related PreviewTrigger and Popover implementation; done means the outer preview remains open while the pointer moves into and interacts with the nested popover.
