title: I can't get code to post in a question - it "appears" there is unformatted code but there is not
body: <p>I have spent almost two hours creating a new question, trying to provide helpful information and code - I couldn't use a code sandbox because sqlalchemy and flask are not available on codesandbox.com as dependencies.</p>
  <p>When I get to the &quot;review&quot; step of my post, I get an error that says:</p>
  <blockquote>
  <p>Your post appears to contain code that is not properly formatted as code. Please indent all code by 4 spaces using the code toolbar button or the CTRL+K keyboard shortcut. For more editing help, click the [?] toolbar icon.</p>
  </blockquote>
  <p>Of course the key word here is &quot;appears&quot;.  There are about a half-dozen code blocks but they're all formatted correctly.  I've tried using three tick fences, tried using control-k to format the 4 spaces, tried using both methods together, and I keep getting the error.  There's not enough detail in the error to tell exactly where the stackoverflow code thinks there is unformatted code.</p>
  <p>Any suggestions on how to get past this error?</p>
