LPS-44171 Advanced Search hides context after search is performed

Hey @jonmak08

Right now in a few navbars in portal there is an issue with the mobile search toggle button

(this one)

In a few use cases it doesn't toggle the aui:nav-bar-search correctly, just know it's not caused by either of these commits. I think I know what the issue is so I can look into it.
