Add New button not disappearing in Distraction-free Writing mode

[ahortin]

When using the Distraction-free Writing mode while editing a Page or Post, the Add New button no longer disappears. This bug seems to have been introduced in 4.7 as it was working fine in 4.6.

Here's a screenshot of what it looks like now:

The Add New button should disappear as it did previously, along with the other elements. Not only does the button look completely out of place, just sitting there on its own above the title, it makes no sense to keep it displayed.

This is a regression caused by [38983]. Moving to the next minor release for consideration.

In 39619:

Editor: Let the Add New link disappear in DFW mode.

The link was moved outside the heading in [38983].

Fixes #39313 for trunk.

Just tested this and that patch works fine.

Thanks.

Yes, patch looks good. It's not major, but good to fix in 4.7.1 imho.

In 39634:

Editor: Let the Add New link disappear in DFW mode.

The link was moved outside the heading in [38983].

Merges [39619] to the 4.7 branch.
Fixes #39313.
