Bug: Missing move selector in studies

When you have more than one continuation for a line, you can't access the alternative lines anymore per keyboard. There used to be a list of links allowing you to select a move per arrow up/down, but that seems to be gone completely. Please bring it. back. :)

I also don't like how the font size in subvariations gets smaller and smaller until it's barely readable.

Example: lichess.org/study/4Aqycynk/qULiM6L4

Browser: Vivaldi 2.2, running on the Chrome/71.0.3578.98 engine.

Update: The same problem exists on the analysis board. I also checked it with the latest updated Chrome, and I could reproduce the bug in that.
