Heredoc wrong colors

[collimarco]

I have a simple heredoc like this:

content = <<~DOCKERFILE
 The content of any Dockerfile here
DOCKERFILE

You will get a strange / completely random coloring of the syntax inside the heredoc.

Expected: only one color (green) for all the content, since it is a string, OR the Docker syntax coloring.

Actual: random colors not consistent (for example RUN has different colors depending on the line)
