Keyboard Navigation through grid looses focus

Select one Segment use ↓ multiple times (don't keep pressing) to select next segments. After about 100 segments use ↑ to go up again. It can happen that the focus is lost and the grid header column menu is focused and traversed then via arrow keys. If not reproducible try different speed of using the arrow keys.
Reason is probably the rebuild of the HTML on re-rendering the segment content.

Usually the grid table view renders about 50 Segments in the HTML. If one gets to the end of that 50 rendered segments the next segments are rendered in HTML. If one presses the arrows keys in that phase I assume that then the focus jumps outside of the grid.

Possible Solution: Invoke into grid keyboard navigation, ignore the navigation events if HTML of grid table view is not ready.

This issue was previously part of TRANSLATE-1128. Since it has a different cause than the rest of TRANSLATE-1128, it was moved into a separate issue.
