Treegrid - empty gridcell is not handled properly

[kolaps33]

Steps to reproduce:

1. Run NVDA

2. Navigate into example: https://codepen.io/amberpie/pen/vYqzGvM This example comes from ARIA example: https://www.w3.org/WAI/ARIA/apg/patterns/treegrid/examples/treegrid-1/ There is difference that this example uses div and applies on it proper aria-roles.

3. Navigate into "gridcell" in the first column in the first row.

4. Press "CTRL+ALT+Down Arrow " using NVDA in browse mode

5. Press "CTRL+ALT+Down Arrow " using NVDA in browse mode

Actual behavior:

out of table out of frame blank clickable frame table with 3 rows and 3 columns row 3 column 1 link someone@please-do-it.company

Expected behavior:

row 2 row 3 link someone@please-do-it.company

Comments: NVDA doesn't handle empty gridcell properly. It narrates out of table out of frame. When user navigates to another not empty gridcell, then it narrates again the whole table information such clickable frame table with 3 rows and 3 columns.

When we use identical example: https://codepen.io/amberpie/pen/jOjvqjy which use native html markup (tr, td,), then the NVDA narrate empty gridcell properly.
