I think at this point we could fix the annoying `@ident.` completion problem: It would be a bit of a hack, but if the partition corresponds to an HTML partiton consisting of only a dot, we could return the previous partition. For some reason, even though we take this path, the HTML partition length is `2`, and we end up returning the same HTML partition.

Just a note for the future, this is behaving the same as the previous editor.
