How do you reproduce the problem?

1. Visit https://www.patternfly.org/components/popover/#basic
2. Click Toggle popover button.
3. Scan page with axe DevTools and ignore the last issue as irrelevant.

Expected behavior

Render markup that passes axe DevTools rules.

Is this issue blocking you?

No, we will fix 10 occurrences as follows:

1. Move occurrences of footerContent, or headerContent, or both, to props of a pure presentation component that composes them with bodyContent and returns markup for bodyContent prop of Popover element. That is, replace footer and header elements with div elements that have PatternFly classes for same visual appearance.
2. Render (instead of heading element) p element that has PatternFly class for same visual appearance, but takes out of heading hierarchy of page. Similar solution as our workaround component="p" prop for Alert elements that do not seem to fit heading hierarchy of page.

Any other information?

Popover コンポーネントと patternfly.org/components/popover/#basic の基本的な Popover の例から始め、axe DevTools で報告された違反を再現します。10 個の箇所を更新し、footer と header のコンテンツが landmark ではないプレゼンテーション用マークアップを使用するようにし、デフォルトの header が不適切な見出しレベルを追加しないようにします。報告された axe ルールに合格すれば完了です。
