[TYPO3-english] CKeditor problem after update to 8.7.6

[swanage]

After updating from 8.7.4 to 8.7.5 and finally to 8.7.6 Ckeditor gives me problems.

When changing format of text (not being paragraph, f.e. in heading 3) the text gets wrapped by the p-tag:

F.e. "test" shows:
<h3>test</h3>

source:
<p><h3>test</h3></p>

Anyone else having this same problem?

I have an issue with own classes for p and span Tags. Since the update the classes are always removed from the tags. With Typo3 8.7.4 I haven't got this issue... With a Tags and Headlines i don't have this problem, I'm still able to use own classes...

I already submitted a bug on forge, issue 82476
