When WebKit WPE port is built using gcc 13.2.0 for nxp imx8mp (aarch64-poky-linux-gcc, aarch64-poky-linux-g++) font face API is basically not working as it's not loading font faces.
It turns out the problem is here: https://github.com/WebKit/WebKit/blob/9878e30a6f7350aca54e860251f34971e6aed1f6/Source/WebCore/css/FontFace.cpp#L87 and what happens is, dataRequiresAsynchronousLoading lambda capture (by reference) behaves as if it was capture by copy and therefore even tho we set the value to false in lambda, the dataRequiresAsynchronousLoading is true after WTF::switchOn() call... So it's likely some compiler bug as e.g. disabling optimizations for that function using #pragma GCC optimize ("O0") helps.
