WebM Alpha VP8/9 Rendering Is Buggy

So, I tried Kdenlive 21.04.1 and for some reason and I don't know why but when I tried to render a RGBA WebM with Transparency, it broke the video file by either having a Totally Black Video or a Blinding White Video. Because of this, I am reverting back to 20.12.3 and see if the issue is fixed in the previous version.
