When I added some keybind shortcuts("bmir + shift+[spacebar+'enter'] ")", I couldn't find any analysis in studies for that feature so I thought it was excluded. Apparently not.

Repro steps I did to realize that :
1- https://lichess.org/broadcast/biel-festival-2023--masters/round-3/ZcQs5amV
2- Search the game with rosen
3- Realize you cannot type 'b' (even if you can flip) to go to the blunder.
4- Then when you enter some studies, you notice that they can (though there are apparently none) analyze.

While testing I noticed that in that same URL [when the page is initially loaded, and the "close-up" board isn't loaded yet] you can use the keybinds, but with 'Flip' (f), since it uses chessground and that it is undefined, it errors. [Cannot read properties of undefined (reading 'set') @ analysisBoard.study.min.js:39

Fix coming soon™.
