Description
### Summary
I needed a quick break from macOS backend work, so I'm looking at modernizing and cleaning up the `web_backend` JavaScript files. They currently use a mixture of outdated JavaScript syntax while also using modern web browser features like ResizeObserver.
I noticed that we removed the ResizeObserver ponyfill in #31669. Do we have an official policy on which specific web browser versions we support?
For example, we have code to check CanvasRenderingContext2D.backingStorePixelRatio; however, that property was never official and removed around ~2015. We also warn if a WebSocket doesn't support binaryType; however, [it has 100% tracked user support on caniuse](https://caniuse.com/?search=binaryType).

Research direction
Start by reading the web_backend JavaScript files referenced in the issue and the discussion around #31669, then review the existing browser capability checks. Done means the project has an agreed policy for supported browser versions and the outdated or unnecessary checks are identified for cleanup.
