False positive for Rails/OutputSafety in Multiline Heredoc

[dari-us]

For multiline heredocs, Rails/OutputSafety complains when calling #html_safe.
Single line heredocs are no problem, though.
It is a "heredoc literal", i.e. I am not using interpolations.

---

Steps to reproduce the problem

# registers offense
<<~HTML.html_safe
  <h1>nice content</h1>
  <h1>this is cool too</h1>
HTML

# registers no offense
<<~HTML.html_safe
  <h1>nice content</h1>
HTML

Expected behavior

Rails/OutputSafety should not register an offense for any of the above examples.

Actual behavior

Rails/OutputSafety registers an offense for the multiline heredoc.
