Subject: [PATCH] Differentiate comments with and without brackets

Per T205581#4768548 cached HTML might render a comment with
double brackets in the text. The CSS selector should not apply
there so a new class is used.

Using a BEM convention for the time being. This class can be
removed in future if needed.

Bug: T205581
