1. Create a Dockerfile with the following content.

#escape=x
FROM x
E

2. Invoke content assist on the third line.
3. Nothing will appear.
4. You'll get the same result with the following file.

#escape=
FROM x
E

-----------------

The Dockerfile builder only accepts backticks (`) and backslashes (\) as a valid escape parser directive.
