Exact URL of where the bug happened

During a game, when reloading the page you'll have the draw button available, even if it shouldn't be.

Steps to reproduce the bug

1. Start a game
2. Play a move
3. Wait for the opponent to play a move
4. Offer a draw
5. Wait for the opponent to decline
6. Notice that the draw button isn't usable anymore
7. Reload the page
8. Notice the draw button is now usable
9. Press the draw button & confirm
10. Notice that the draw offer isn't sent (nor received by the opponent), as this was a UI bug

What did you expect to happen?

The button to still be grayed after having reloaded.

What happened instead?

The button was white and usable, even though it wasn't in reality.
