@voidpumpkin, @mc1098, can you describe what exactly needs to be documented? What are "weird cases" we should expand upon?

@hamza1311 Coming back to this, its probably going to be a bug what i had in mind. Until i test it, i will keep this issue on me as a reminder and either add the docs or remove the statement about "weird cases".

I did not reproduce my issues, this gh issue can be used to just remove that "weird" sentence #2178 (comment)
