Alert Leaderboard mobile performance woefully slow

[Maelstromeous]

Mobile rendering of the leaderboards results in a very poor experience. Loading times are slow for redraws, although do improve once a user searches for something.

Also the headers of the table don't line up with the data upon horizontal scrolling.

Need to investigate if these issues can be mitigated or somehow changed on mobile devices. May have to paginated for mobile.
