Grid navigable isn't working properly in master detail grid

[Faizan]

In master detail grid I set the property [navigable] = "true" in all nested grids which makes me face issue that for example I have expanded a row and select the 3rd(or any) row of inner most grid, so it will first select the 3rd(or any) row of outer most grid and then moves in hierarchy to select the one which I actually want to get selected.  I have recreated this issue ion stackblitz,
following is the link of recreated isssue:

Hello Faizan,

Navigation in Master-Detail Grid scenarios is currently not supported. This is a documented limitation of the Grid accessibility and Keyboard navigation functionality:

If you have the time, please submit a feature request to our UserVoice portal with a brief description of the desired functionality or behavior that you would like to see built-in in a future version of our packages:
