TYPO3 Core

I found after updating a TYPO3 project and introducing site configs and TCA type slug fields to custom TCA tables for url handling, that in the CMS backend trying to edit records containing a TCA type slug field and having sys_language_uid -1 (All languages) the backend throws an exception:
"(1/1) #1522965188 InvalidArgumentException Language -1 does not exist on site #PSEUDO_2."

So I guess the TCA type slug can't handle sys_language_uid -1 as this can't be a defined language in site config, which can only contain languages with uid > 0.

Stacktrace:
