I can confirm that. Also applies to "header".

TYPO3 11.5.9
frontend_editing 3.0.17

Im my case, under TYPO3 11.5.1 and frontend_editing 3.0.18 the bug also present.

I've noticed that the p-tag is added when editing is started and the placeholder is emptied.
When you delete the p-tag by inline-editing, you can work like expected and the p-tag stays removed.
