A11y - tab stops-selection by tab key goes under locked columns and becomes invisible.

when jumping in the title of the table, selection goes under fixed columns and becomes invisible, it scrolls the table to the right after few more jumps.

The demo below is to simulate our business scenario

3oqybd (forked) - StackBlitz (code)

react-t4bmp9.stackblitz.io (Open the page verification tab stops)

As you can see in the picture above, the first and last columns are locked, because the grid's scroll bar is for the entire table instead of the unlocked column.
So when using the tab key to select the fourth and fifth columns, since the width of the Grid has not yet been exceeded, the scroll bar does not scroll, resulting in the selection of the fourth and fifth steps being invisible under the locked column

The scroll bar only scrolls when the tab key reaches the sixth step.

How could I solve this problem? please let me know if you have any questions?
