No working option to analyse games/positions from private studies

Somewhat related to #19

I wanted to analyse a position from a game linked in a featured blog post. But as the 3 options "Analysis board", "Practice with computer" & "View on Lichess" redirected to the same link, and because the study was set to private, I couldn't access it.

I didn't expect to be able to access a private study (and maybe private studies aren't meant to be shared in a public blog post?) but I thought I could analyse the game/position after clicking on one of the 3 options, rather than copying the PGN/setting up the position myself.
