As I mentioned, I can't reproduce it here. I do find that the presence of a space is crucial. It is necessary to type a space after having typed the number, for the conversion from typed to automatic numbering to occur, but your screen shot certainly looks like there is a space present.
Does this problem occur in one particular document, only, or in all documents that you edit in Word Online?
