    [WPE][GTK][Debug] Crashes in imported/w3c/web-platform-tests/reporting

    The C++ standard doesn't define an order of evaluation for function arguments, so without forcing it
    when creating the report we might trigger a use-after-move. This was specially noticeable on GCC
    builds, not so much with clang.
