We shouldn't be calling `sys::path::native` repeatedly inside the loop.
```suggestion
  SmallString<128> RelativePath = computeRelativePath("", InfoPath);
  sys::path::native(RelativePath, sys::path::Style::posix);
  for (const auto &FilePath : CDCtx.UserStylesheets) {
    SmallString<128> StylesheetPath = RelativePath;
    sys::path::append(StylesheetPath, sys::path::filename(FilePath), sys::path::Style::posix);
    StylesheetArr.getAsArray()->emplace_back(StylesheetPath);
  }
```
