Post slug editor does not appear although it's activated

[jottlieb]

From here: ​http://trac.wordpress.org/ticket/8173

The post slug module won't appear although the 'post slug' checkbox in 'screen options' is checked. Only on unchecking and checking the checked checkbox again, this module appears (until you leave the edit page. You have to do that every time, you want to edit the post slug).
It also does'nt appear after autosave.
And another question is: Why do blogs with permalinks enabled (other link structure) have two ways of editing the post slug (edit permalink and post slug module)?

Default: post slug module is activated, bus does not appear

The slug box is intended for fallback when JS is not available. It showing up in the Screen Options is an artifact. It should be removed from Screen Options for 2.7.

@ryan:
Removing it is imho no option. Because if you have the default link structure enabled, the permalink slug editor will not appear. And so there would be no possibility to change the slug when using default link structure. And that's bad.

[ryan]

Patching screen options to properly handle hidden by default boxes is probably too much change this close to the final release. This is not a regression since 2.6 so removing the slug screen option is definitely an option. If someone provides a solid, tested patch, we might be able to get it in.

(In [9956]) Hide slug box by default. Allow turning it on via screen options. fixes #8332
