Comment (by azaozz):

 Happens because post.js (containing most of the JS for the Add/Edit Post
 screen) requires heartbeat.js. If the latter doesn't exist, the former is
 not loaded.

 We probably can change that requirement, however heartbeat is needed for
 autosave, auth-check, post locks, etc. Deregistering it will disable all
 of them. If the purpose is to reduce AJAX requests, opened #29779 for a
 better way.

 Thinking this should be 'wontfix' in favor of #29779.
