To me it seems like she was feeling insecure in herself. You acting calm and strong around her possibly makes her take a look at her own actions. The hat and sunscreen, in her eyes, may have seemed like a challenge to her parenting ability. When your breaking up your family and know your being a bad parent anything small that reminds you of that wouldn't be welcome. Just a theory, could be wrong.
IC explained this possibility with my W's own anger that occasionally comes up. When I asked her not to bring children around OM she was furious. He said in her eyes I was reminding her of the choices shes making for OM and what shes doing to her family. They don't like being reminded of those things. Easier to just blame another and not think about it.
Basically, her anger is about her, not you.
