There seems to be something wrong with the makdown list

Hello, in markdown mode, when I enter "1. " and then press enter key multiple times, this "2. " will follow the optical cake and will not be deleted automatically. Is it specially set like this?

Yes, more or less. You can press backspace to delete the marker. But since it doesn’t make much sense to move a list marker more than two lines beyond the previous item, I’ve pushed a patch that makes it delete the marker on the third enter press.

ok, very thanks
