Perhaps the same root cause as #33017.

Here's a reproduction using react@17 and adding a FluentProvider wrapper to ensure proper styling https://stackblitz.com/edit/vitejs-vite-ztxunm?file=src%2FApp.tsx

I believe this issue and #33017 are the same. In this example provided by @tvandalovsky the Popover is with trapFocus attribute and the logic behind PopoverSurface includes aria-modal=true and role=dialog to the popover once trapFocus is true.

fluentui/packages/react-components/react-popover/library/src/components/PopoverSurface/usePopoverSurface.ts

Lines 53 to 54 in fc7240b

	role: trapFocus ? 'dialog' : 'group',
	'aria-modal': trapFocus ? true : undefined,

This is only reproducible with trapFocus attribute on. This leads me to believe it might be related to some modalizer logic on tabster. Even after adding inline to the Popover the problem remains also 🤔

@mshoho is this a known issue on tabster?
