[2023] Banshee's Veil cooldown disables Malzahar passive shield until the Banshee's shield is back up. Is this an intended mechanic or what is up exactly?

So I've been playing Malzahar and I noticed this thing. Banshee's is an item I would sometimes buy vs AP heavy teams.

Also having 2 shields is kinda nice. Makes you very safe.

But I noticed late game that when both shields are popped, my passive doesn't come back until the Banshee's shield does.

Maybe this is intended but it feels super weird... Kinda like they share the same code or something.

Can anyone clarify? If it's intended it's certainly not made clear anywhere when reading Malz's kit.
