Meta-boxes don't behave as normal on edit comment page

[bbrooks]

The following was noted on trunk rev.21,458

On the edit comment page, meta boxes added by plugins (like Akismet) are not collapsible or rearrange-able.

Also, unchecking meta boxes in the 'screen options' in this context does not hide them as expected

To reproduce:

1. Add an arbitrary meta-box to the edit comments page (Fastest way is just to enable Akismet)
2. Make a comment
3. Go to the comment editor for that comment
4. Below the main text area, try to close or move the meta-box you added in step 1

Best guess is that whatever JS is required for metabox behavior is not loaded on the edit comment page.

And just like that, it works!

Would setting 'postbox' to be a dependency for 'comment' make more sense? Looks like we do this for post, link, and dashboard, though not for nav-menu. Looking at wp-admin/nav-menus.php, looks like a lot of those lines should be removed in favor of dependencies.

That works as well: 21499.3.patch​.

Looking at wp-admin/nav-menus.php, looks like a lot of those lines should be removed in favor of dependencies.

Created #21777 for nav-menus.php.
