[beta.sketch.sh] Dep resolver doesn't work in Safari

When opening https://beta.sketch.sh/ in Safari the console shows:

ApiErrorJson:
Url: https://data.jsdelivr.com/v1/package/resolve/npm/@
{"status":400,"message":"Bad Request. Visit
https://github.com/jsdelivr/data.jsdelivr.com for documentation."}

I tracked this down to an issue with how Url objects are handled in different browsers. It seems that Safari doesn't put in url.pathname the same data as Chrome or Firefox in this line:

sketch-sh/client/src/container/Container_bundler.re

Line 92 in d98d0b4

let pathname = parsed_url->Webapi.Url.pathname->normalize_pathname;
