Menu items no longer spaced apart on WordPress 4.4

We recently updated oik-plugins.com to WordPress 4.4 and noticed that the primary menu items were no longer spaced apart. The same thing happened updating the local version. We’re going to find out why this has happened and see if this is an expected side effect of the update.

Problem explanation

Menu items which used to have white space between them now appear to be bunched up.

Expected output

The menu used to look like this; the screenshot for the theme.

Explanation

This is due to a code change implemented in WordPress TRAC #27762: Remove whitespace between menu items

Proposed solution

I have a couple of choices.

• Add a margin in the CSS for the list items.
• Do nothing; live with it.
• Live with it, but update the theme screenshot to reflect the change.

I wonder how many themes have been affected by this change?
