[2023] This is why remake is bugged, as a matter of fact; it's a feature

Yeah that's not sufficiently detailed. The first blood needs to happen very soon after someone goes AFK in order to prevent a remake. This was built to prevent players from going AFK to remake a game if they had a poor jungle invade or something. It's not precise because we can't tell the exact moment someone goes AFK (as opposed to just stopping for some reason), so it is possible for a first blood to happen after you see someone go idle to prevent a remake. However, if someone is AFK from the start of the game, you should still get a remake vote even if there is a first blood afterwards. If you can dm me info about the game, or capture a video following the AFK player in a replay, I can poke the team about it.
