Additional notes

  • attached screenshot with the main issue;
  • same issue for other sub-sections as well; the Security sub-section has a collapsible element that can be toggled but the focus ring is still on the whole sub-section;
  • the Response and Params sub-sections require 2x TABs to show the focus ring;
  • the Stack Trace sub-section has an expected behavior, as in the focus jumps on the next element and not the whole section;
Has Regression Range: --- → yes
Has STR: --- → yes

Thanks for the report!
