Top navigation obscures save button on small window sizes

[dancgray]

Expected Behaviour

Should be able to click the save button when editing an ABC etc

Actual Behaviour

When the window is smaller (depends on the length of the users email address) the save button is covered by the navigation-inner div.

Steps to Reproduce

1. Edit an artcile, block or component
2. Reduce the window size to below 750px wide (depending on the size of the users email which is displayed in the navigation bar)
3. Notice that as least some or all of the save button cannot be clicked
