Marching ants test selection animation doesn't work across multiple pages

[ryandem1]

Marching ants test selection logic currently only works across a single page. The logic needs to be updated to work on each pagination page independently.

Minimum reproduction

1. Start with enough tests in the tests table to enable at least 2 paginated pages
2. Select the test in the first table index
3. Navigate to another page of tests
4. Select the test in the second table index

Issue: The selection animation in the second index behaves as if the test above it was selected, when it was actually only selected on the first page. It becomes more problematic if you are doing a lot of selecting/deselecting across multiple pages because the animation gets all kinds of screwed up.
