Browse Tree doesn't load more than 24-25 worlds in a category.

Verification builds: 1.7.0.2 - R7 Beta 21 Build 1117901

Summary:

When clicking through Browse Tree in 1.7, for example clicking "Adventure Map" it says "72 Results: Adventure Map" however scrolling through the list only shows 25 and no extras load.

Impact:

This results in content being buried and so, less potential sales if players don't find what they're looking for.

Repro Steps:

1. Open the Store.
2. Press Worlds
3. Press Adventure Map

Observed Results:

Adventure Map category it shows "72 Results: Adventure Map", but scrolling down only shows 24 maps.

Mini-Games category it shows "53 Results: Mini-Games" but scrolling down only loads 25 maps

Survival Spawn category it shows "93 Results: Survival Spawn" but scrolling down only loads 25 maps

Expected Results:

The categories should keep loading and be displaying as many maps as there are in the results found, and not stop at 25.
