Syntax highlighting broken in Markdown with inline comment at method definition line

[AlexWayfer]

Description

In the title.

Steps to Reproduce

Have a Markdown code like:

You can handle errors by protected #server_error method with exception argument
(calling super is recommended).

def index(method)
  raise 'Error'
end

protected

def server_error(exception) # => 'Error'
  @my_var = true
  super
end

Private methods for helpers (model_params, for example).

Get current response body: body. Set: body 'New body'.

Expected behavior:

Normal Makrdown highlighting after Ruby block:

Actual behavior:

Broken Markdown highlighting, like it's still in a Ruby code block.

Reproduces how often:

100% with the comment at a line with def.
