Lack of NVDA support on grids

Hello Web Aim team,

Recently while working on grids (editable tables), observed that there
is a lack of support by NVDA.
In grids preferable design pattern is -
1. When cell contains only textual information then whole cell receives focus
2. when cell has only one interactive asset, like a link, then the
asset inside the cell should receive focus.

Now, following this pattern, found that when we move from focused cell
to the adjacent cell having link getting focus, using arrow key
navigation inside the grid, NVDA is coming out from focus mode to
browse mode and then ofcourse further arrow key navigation will not
let focus go into focus mode. This is not observed with JAWS.

I checked the APG WAI example for 'Data grids' and found the same
behavior there as well. Example link -

Any help to suggest how to handle this better or is there any issue
flagged to NV Access for this?


Secondly, using Voice over on MAC - safari, do we have this concept of
focus mode versus browse mode?
Means can we navigate in grids using just arrow keys on safari browser
using voice over too?
