Crosstable hover feature malfunctions

[mmixu]

What happened

There's a bug where the position of previous games aren't visible when hovering over the crosstable.

Steps to reproduce the bug

1. Go to https://lichess.org/tv
2. Hover over a game in the scoreboard
3. You should see a grey box instead of the miniboard position

Additional information

Live miniboards seem to be fine.

Hmmm I think this is ricochet from this commit https://github.com/lichess-org/lila/commit/037bfcc00078ca45b3021da931e90ca83b832de9
