Summary

Many client-side JavaScript frameworks currently use case insensitive URL matching. URLPattern, however, follows URL semantics and treats many parts of the URL as case sensitive. This feature adds an `ignoreCase` option to the URLPattern that switches all matching operations to case insensitive for that given pattern.
