TYPO3 Core

RTE inserts "<p>nbsp</p>" into translated content items.

When I try to translate a content element (text & pic) from the original language to another language, it works fine for the first time.
In the backend as well as in the frontend the texts are first displayed correctly.
But as soon as I open the translated text for editing, the RTE inserts a <p>nbsp</p> between the first sentence and the H3-heading.

I was able to reproduce this behavior on a bare TYPO3 instance (version: 8.7.26) without RTE Configration.yaml, as well as on a TYPO3 instance (version: 8.7.26) with RTE Configuration.yaml.
