Screen reader keyboard navigation skips cells when columns are virtualized

[jtribe32]

Provide a general summary of the issue here

When navigating a horizontally-scrolling table that uses TableView with a screen reader, arrow key focus moves before React renders the virtualized cells. This causes focus to skip over cells that aren't in the DOM yet, jumping to the end of the row instead of the next column.

🤔 Expected Behavior?

Arrow key should focus on the next column in the table when using a screen reader

😯 Current Behavior

Pressing the arrow key at the end of the rendered page, skips several columns when using a screen reader
