Extension inserts snippet 1 line higher #62
Description
When typing, for example, for i arr and hitting the shortcut, the for-loop is inserted on the line above the one I typed for i arr. This happens with templates defined in the .json files as well as in the .snippet files.
A bigger problem is when trying to insert on the first line of the document: the extension tries to insert on line -1, which obviously doesn't exist, so CodeMirror throws an error and the snippet is not inserted.
