Eui: Cannot add data-test-subject to the arrow which expands sections in side nav

[bhavyarm]

I was fixing a skipped a11y test on Kibana home under x-pack and ran across this problem. I cannot add data-test-subject to this part highlighted in red circle. This is in src/core/public/chrome/ui/header/collapsible_nav.tsx

 collapsible_nav.tsx

Hey @bhavyarm , I'm working this one out for you. Quick question, are you specifically trying to target just the arrow icon? I assume you actually just need a data-test-subj on the whole accordion triggering button which actually includes that whole heading in your screenshot (Logo and "Analytics").

Yay Thanks @cchaos - we just need it on the whole accordion triggering button. cc @myasonik
