 Usually within the WYSIWYG, you can click on an image you've inserted and
 get the contextual menu to make some edits to it. I'm currently getting a
 JS error anytime I try to click on an image:

 WordPress 4.7.3. I've deactivated all plugins and reverted to a default
 theme (TwentySeventeen) to no avail.
