Funnels do not block off Tunnel faces

[CenTdemeern1]

Description

When using Andesite/Brass Funnels & Tunnels, placing a Funnel on a side of a Tunnel where it connects to a Belt does not plug the Tunnel.
Instead, the open Tunnel face stays open underneath, and thus a Redstone-powered Belt Funnel attached to a Tunnel can't be used to conditionally redirect items out of a Tunnel onto another Belt as expected.

This is unexpected behavior, because this does happen with blocks like the Basin, where the output gets blocked off if you place something like a Funnel on it.

Notice how the Funnel is powered by Redstone, so it shouldn't take out any items. The open Tunnel face underneath is taking a single item off of the stack.
If this was working as expected, the Funnel should take the full stack out of the Tunnel when unpowered, and take out none when powered.

Notice how the open Tunnel face isn't visible (completely obstructed by the Tunnel) and thus is probably not expected to be active.

Notice how when using Spectator Mode, the Tunnel face is visible, but is almost completely blocked by the Funnel's connector.

This is intended, funnels and tunnels are not meant to be used together like this
