Field output as HTML?

[pboling]

In my model:

  def array_of_stuff
    [
      1,
      2,
      3
    ]
  end

In my config:

        - field: array_of_stuff
          header: cool things
          method: multiline

In my helper utils class:

class MyHelperUtils < TinyAdmin::Support
  def multiline(array, options: [])
    array.join("<br/>") # Doesn't matter if I append `.html_safe`, or anything else I've tried
  end
end

Page Result in the browser (<br/> tags appear as raw text, not as HTML):

1<br/>2<br/>3

The above is wrapped in actual HTML <span> open/close tags.

Is there a way to have a helper output HTML and have it render as HTML?
