If a data table row has been modified, two clicks on another row are required to switch

The row selection doesn't update on the first click if the previously selected row had been modified. This is likely because we cache the selected row before updating the data table to reflect the new value. We may be restoring that cache after moving our selection to the new row, thus overwriting the variable back to the previously selected row.

1. Create a data table
2. Add some rows
3. Click on a row
4. Edit some values in the Row Editor
5. Click on a different row
6. The value will commit, but the row won't change to the newly selected one
