This is so weird !!! I can repro on my phone and knowing both render the exact same now, this does not make any sense… This is unfortunately not something we control, could you log a bug for webkit ?

Hello @Zion_Huang just checking in, are you still having issues? Were you able to file a bug for webkit? :slight_smile:
