Question about steam flatpak

I looked around and didn’t find a satisfying answer to this. I usually use flatpak to install steam, so I don’t need to enable the multilib repos. When installing steam via flatpak it lists components it’s going to install. Two components are called GL and GL32, which are mesa drivers (extensions) according to the official site.

Now my question: Are these drivers used over the system drivers installed on my machine? So if mesa 22 is released inside the official arch repos in the next couple days, will steam flatpak use it? Or will I have to wait for flatpak to update their version inside those components and do flatpak update?
