- not going to try anything fancy here, class components are a headache
+ array `.map()`
- a neat example of DRYing out existing perf attempts!
- no usages in Kibana
- `optionalChildren` isn't worth memoizing because children rerenders too often + move `.euiCallOut__icon` to header styles since it's only used in that DOM
