Fix drawer drag dropping by itself when the search keyboard was open

Starting a drag clears the search focus, which closes the keyboard and flipped
the drawer between its scrolling grid and its pager. Every cell, including the
one driving the drag, was recomposed mid-gesture, so the icon was placed as if
the finger had lifted. The layout mode is now frozen while a drag runs, and an
item gesture torn down mid-drag cancels the drag instead of leaving it orphaned.
