None (Header menu is everywhere)

<ins>Steps to reproduce</ins>

1\. Open search menu by clicking on the magnifier
2\. Enter arbitrary text
3\. Tab outside the Window/Tab

<ins>Actual</ins>

- search window closes

<ins>Expected</ins>

- search window stays open

Note: I realize that there is a need for closing the search window at some point. The problem is that the current solution might be too eager and thereby confusing. A more sensible approach would be to:

- Begin of the insertionleaveEnd of the insertion Begin of the deletion closeEnd of the deletion the Begin of the deletion searchEnd of the deletion box Begin of the insertionopen when input’s content is non-emptyEnd of the insertion Begin of the deletion on **click** outside the search boxEnd of the deletion
- close the box when the user hits `ESC` while focusing the Begin of the insertioninput, clearing content in the process.End of the insertion Begin of the deletion input.End of the deletion

I also advise on using `aria-expanded` (http://www.w3.org/TR/wai-aria/states\_and\_properties\#aria-expanded) to show whether the input is expanded or not. Begin of the deletion
End of the deletion
