  Make codrops WebGPU demo load in Safari

https://tympanus.net/Tutorials/WebGPUFluid/ is a really cool WebGPU demo
that works with WebKit's WebGPU implementation.  However, it relies on a
Chrome-only loading behavior that immediately fails to load URLs that have
a newline and a less than character in them, specifically with this line:
try{return await(await fetch(n)).text()}catch{return n}
Chrome doesn't even try to load the string as a URL, Firefox and Safari do.
This adds a quirk to make the variable in their JS named Hr hit the same
load failure as it does in Chrome, which then lets the page proceed to
load the demo.
