Elytra not rendering properly when using “Pancape” cape

When wearing the “pancape” cape and the elytra item at the same time, the wings of the elytra become invisible. This is probably only visual because you can still use the elytra.

The issue was marked as fixed and a new pancape texture was added. For some days, It was working fine and the elytra appeared with the new “buttery” texture. But today, for some reason, it stopped rendering.

I have also attached a video recreating the problem
