RAC Virtualizer content element should have role="presentation"

[majornista]

The generic div container that wraps the virtualized elements and provides the content height for native scrolling should have role="presentation" so that it does not break the accessibility tree structure for the containing grid, menu or listbox.

react-spectrum/packages/react-aria-components/src/Virtualizer.tsx

Line 65 in 2cd8f0b

<div {...contentProps}>

The problem can be seen in the Virtualized RAC table at: https://reactspectrum.blob.core.windows.net/reactspectrum/ff19a7c1ca7fccfd3e46eeef1c6b71ef23f36437/storybook/index.html?path=/story/react-aria-components--virtualized-table&providerSwitcher-express=false

We may wish to return role="presentation" at:

react-spectrum/packages/@react-aria/virtualizer/src/ScrollView.tsx

Lines 245 to 247 in 2cd8f0b

	contentProps: {
	style: innerStyle
	}
