        <pre>STEPS TO REPRODUCE:

1. Capture enough snapshots so that the Snapshot List table has scroll overflow.
2. Scroll down to the bottom.
3. Select two snapshots with &quot;Compare Snapshot&quot; button
4. Re-select &quot;Snapshot List&quot; path component in the secondary navigation bar.

EXPECTED:

Scroll position within the data grid is restored

ACTUAL:

Scroll position is reset, and data grid appears empty until scrolling forces relayout/repaint

NOTES:

It looks like the data grid scroll position is reset to top, but the styles of the rows are not re-synced to that position.
I think it's fine to reset the scroll position since we don't integrate secondary view changes into our back-forward list. But, the view shouldn't be blank!</pre>
