<p>If a person has edit privileges, the screen for editing questions appears as @whuber describes - all answers and comments remain visible.  If you don't have edit privileges, you can only see your own question, as in the question.  I have edit privileges on StackOverflow but not here on CV, and here's the difference:</p>

<p>A random question on StackOverflow, where I have edit privileges:

<p>My own question on CrossValidated, where I do not have edit privileges:
<img src="https://i.stack.imgur.com/BzpGM.png" alt="enter image description here"></p>

<p>... which raises the question of why that difference exists at all.  It seems like viewing answers and comments would be equally useful for anybody editing a question.</p>
