How do I give this bug a thumbs up? Asking for a frustrated friend...

[ItaloLeandro02]

Froala 4.2.1 does not have this issue.

[coreequip]

This bug still present in v4.3.0.

Steps to reproduce:

• Just start a (un)ordered list
• press TAB two times

It will end up in a 3rd level list item and the editor is throwing the mentioned exception.
