It's not only a minor styling issue, it's also about doing the right thing. You're basically ignoring "maxwidth - 2*paddings" and displaying content differently.
To quote @Jdlrobson yourself:
When focusing search or editor, the close icon should match up with the content area and the hamburger icon. 
You've written this patch to fix the spacing issue, but ignoring the new spacing issue.
