MD WebUI: Ensure the search field opens on touchscreen tap

This fixes an issue where after touchscreen tapping the search icon, the
browser would return focus to the search icon, immediately closing the
search field. Using the native 'click' event instead of the simulated
'tap' event fixes this issue.
