Enable multiline annotation markers in snippets #36
Description
Currently, certain sections of code can be annotated inside a snippet with a message. This message is attached to the snippet via an annotation marker, which highlights the section of code that the message belongs to. However, currently there is an issue when the annotation marker wraps around multiple lines. In that case an InternalError is raised and the snippet is not displayed. The affected function is called createAnnotationMarker in src/util/snippet.ts.
