This patch mostly looks good. All that’s missing is the changelog highlights that should go in each theme’s readme.txt file.

Gah, thank you for catching that, @allancole! :| You'd think I'd never done this before.

Creating a new patch now!

46070.2.patch​ should be correct -- @allancole can you please take a second look when you have a chance? Thanks!

[allancole]

I think this looks good @laurelfulford
