Lists not working with default RTE

I've tried to find a fix for this but failing.

Problem occurs with:

    __onKeydown(event) {
    if (event.key === 'Enter') {
      this.doc.execCommand('insertLineBreak');
      event.preventDefault();
    }
  }

Which, when creating a list is not the desired behaviour. Only thing I can think of is adding another property to the RichTextEditor class that holds the current action in use, something like:

    syncActions() {
      this.getActions().forEach(action => {
        if (this.actionbar) {
          if (!action.state || (action.state && action.state(this, this.doc) >= 0)) {
            const event = action.event || 'click';
            action.btn[`on${event}`] = e => {
  
              // add action
              this.currentAction = action
              
              action.result(this, action);
              this.updateActiveActions();
            };
          }
        }
      });
    }

    __onKeydown(event) {
      // check the property for something that we can use to determine if to insert line break
      if (event.key === 'Enter' && this.currentAction !== "something??") {
        this.doc.execCommand('insertLineBreak');
        event.preventDefault();
      }
    }


But then, what could be used in that conditional?
