Steps to reproduce:

1. Open the CodePen example
2. Press tab to move focus to the first ARIA gridcell in the ARIA grid in the example
3. With focus on the gridcell press tab to move focus into the ARIA document nested inside the ARIA gridcell. (Focus should be on one of the anchor elements.)

Actual behavior:

When focus moves inside the ARIA document NVDA doesn't automatically toggle the virtual cursor on to allow for object navigation or text to be reviewed within the document to be reviewed.

Expected behavior:

When focus moves inside the ARIA document NVDA should automatically toggle the virtual cursor on to allow for object navigation or text to be reviewed within the document to be reviewed.
