Image URL Bug when typing text while editing of post

When writing text right in the first line under the inserted image markdown, the text is shifted into the line above, breaking down the URL text markdown. Also when Enter key (or Shift + Enter) is opressed in the end of URL markdown, the URL makrdown is broken. It is particualrly affecting editing if the URL markdown is inserted in the end of the post, effectively preventing from adding additional text line when pressing Enter.
