TYPO3 Core

Hello,

I have a problem in an extbase extension with using CKEditor for FlexForm fields, where you can dynamically add elements (defined here: https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/DataFormats/T3datastructure/Elements/Index.html#elements-containing-values-value-elements)
When adding an instance and entering more than 1 line of text/hitting enter after the first line, an additional line feed <p> </p> is added after
each line and every <br /> Tag is converted into a <p></p> tag.

I already tried various different configs for the CKEditor, including setting autoParagraph to false, but to no avail.

TYPO3 Version: 9.5.16

Example:

- before saving

<p>Example 1</p>

<p>Example 2</p>

- after first saving

<p>Example 1</p>

<p>&nbsp;</p>

<p>Example 2</p>

- after second saving

<p>Example 1</p>

<p>&nbsp;</p>

<p>&nbsp;</p>

<p>&nbsp;</p>

<p>Example 2</p>
