Synchronization problem when playing multiplayer browser games like OpenFront

Hello, I’ve noticed that Brave has some issues with somewhat “heavy” multiplayer games like OpenFront. Here’s what’s happening:

When I play the game, everything is fine, but when I switch tabs (for example, I want to change my YouTube music) and then return to the game tab, everything slows down/is out of sync, and it takes a long time to resynchronize with the players.

I’ve noticed this issue also affects Firefox, but not Chrome. Any ideas? Do you think it’s related to Brave?
