Steps to reproduce the bug

Steps to reproduce the behavior:

1. Put grid mode if you are not already using it (settings -> appearance -> list view mode -> grid)
2. Search a channel
3. You will get the channel in the first results, with its popular / recent videos.

Expected behavior

I expect the channel item to be at a reasonable size

Actual behaviour

The channel item is really small
