Skip substring from backslashing

[antonioValenti-enuan]

Hi everyone,
I need to skip some substring from being parsed by lib that adds unnecessary backslash.

I'm using markdown to adds custom code that I need to be kept untouched without wrapping it with backtick.

Example:
{% if var === "foobar" %}

Result parsed:
{% if var \=\=\= "foobar" %}

Expected:
{% if var === "foobar" %}

How can I get the expected result?
