Did you use polyfills? I guess it's very outdated and don't support some features (it looks even worse than ie11).

From https://support.apple.com/en-us/HT204416:

Apple no longer offers Safari updates for Windows. Safari 5.1.7 for Windows was the last version made for Windows, and it is now outdated.

As soon this browser isn't supported by Apple (even by Apple) since 2018 I'm strongly don't recommend you to use it (and even support). And we won't support it. But anyway, try to use polyfills (see #101 (comment) as example).
