Canvas doesn't render in Safari on iOS

I know its not the typical use case, but using code-server (vscode on a remote server) with browser preview (in iOS) would be a great for web development on iPad, but it appears to render a checkered grid instead of the page.

Looking at the css, there is a css class being applied to the rendered page: .img-hidden{ display: none }. My guess is that this class is supposed to be removed somehow when rendering is finished?

How the page is shown initially:

Turning off the display: none css attribute:

No files or tests are named. First reproduce the checkerboard rendering in Safari on iOS, then inspect where the rendered page receives the .img-hidden class and compare that behavior with other browsers. Done means the browser preview renders the page correctly on iOS without regressing other supported browsers.
