Is it possible to include HTML in a fieldset instructions variable?

I'd like to include links to help users when adding page titles, etc. I tried inserting HTML and markdown into the variable but it displayed the HTML directly.

For example:

meta_title:
  type: text
  display: Meta Title
  instructions: The page title you want to appear in browsers. Google has some great advice on how to write <a href="https://support.google.com/webmasters/answer/35624?hl=en">good page titles</a>.
