[BUG][Grid] Unstable selection of embedded tables

[filipKovachev]

if we open a row it jumps to the table, however, when going back it is not possible to return to the table inside the cell. This can be reproduced in the following example with the following sequence:

Tab, down arrow, down arrow, Enter, down arrow, down arrow, down arrow, Shift+Tab, Tab

or Tab, down arrow, down arrow, Enter, down arrow, down arrow, down arrow, Shift+Tab, up arrow, up arrow, down arrow, down arrow, Tab.
