Slower in Leopard than in Scratch 3

It seems that project https://scratch.mit.edu/projects/401788041/ it slower in Leopard than in Scratch 3. To see it working move the mouse around

Behavior I'm seeing is that the project renders 3D planes one horizontal line at a time instead of all at once, so seems like a compatibility issue.

Edit: to devs - labelling as such in this repo but this may actually be an issue with sb-edit sb3 -> leopard translation?

Block basically responsible for rendering is "fill xyz123 color" (fillXyz123Color in generated Leopard). It's "run without screen refresh" but sb-edit doesn't seem to detect that, calls to children custom blocks are e.g. yield* this.rotate(x33, y33, z27) instead of this.warp(this.rotate)(x33, y33, z27). Warp procedure call generation, warp detection.

I made a minimal demo to show the behavior of nested non-warp custom blocks under warp and non-warp ones: https://scratch.mit.edu/projects/715531565/

Code responsible for compatibility here was added in leopard-js/sb-edit#56. That's from January 2021, which is a while ago, so I'd assume leopardjs.com supports it, but... maybe not...?

...Yeah, tested locally, and this minimal project translates as expected. The project linked by @sfederici also works (and runs at 30 FPS pretty easily—Scratch only reaches around 15-20 FPS on my device!).
