TYPO3 Core

In that regard there are some small differences regarding frontend / frontend editing check in RteHtmlAreaApi and RichTextElement.
There are some methods that basically also do the same, maybe the should be moved in a utility?
e.g. there is a isFrontendEditing check method in both that does the same.
Then there is writeTemporaryFile and getFullFilename.
And there is also differences in those two. getfullFilename checks in RteHtmlAreaApi regarding isFrontend() || isFrontendEditing().
In RichTextElement it only checks for isFrontendEditing.

Also the check in writeTemporaryFile has been improved in RtehtmlAreaApi.

Maybe this issue is realted, would have to test it.

are these two related? #65705 #65608
