Page doesn't load on iphone for certain game

[BryceLTaylor]

Expected Behavior

The game loads and runs.

Actual Behavior

This project, https://scratch.mit.edu/projects/280814631/ , loads on mac chrome, but on chrome on ios it gets to the project page and the project shows it's loading. After a few seconds, the whole page becomes an "Aw, Snap!" page.

On Safari it immediately reloads, and the second time redirects you to an error page:

On Mac Chrome, the project loads just fine, but there are warnings in the console:

^ worth noting that second project loads - its after you play it for a few seconds (depending on the phone) it will crash -- seen it crash a different points

I'm not sure if it is the cause but the two projects listed here so far are each trying to send a 0x0 image to webgl. And its sending errors back to us.

The errors may be cascading into crashing the browser tab.

Here are (at least one of) the 0x0 svgs from each project. I captured them from the img.onload in svg-renderer.jsx.
