Input in side menu being triggered by menu button

So, I have a search input within the header of my side menu. Anytime that I click on the menu button, the sidebar menu opens and the keyboard opens up, which is undesired. It does not open up, however, when swiping the side menu open.

I have found other topics referencing an issue with the ghost click function, however have yet to see an actual solution for this issue. Any help would be greatly appreciated!

If possible could you please make a plunker or a codepen for this issue?
