GetURL() on IOS in UE4 and early UE5

Hi Dear Epic & every UE developer:
I notice that in latest UE4 and early UE5 (before UE5.4) version, when try to get URL from http response on apple platform, I can only get query part rather than complete URL.

However, in most platforms, I can get the complete URL string through GetURL() function, which causes return values of GetURL() are different between IOS and other platforms(like Android & Windows).

Thus, I wonder, why the implementation of GetURL() on IOS in UE4 is different? Or it’s just a bug?

TY
