The search input no longer expands to the left when focused, only when there are search results. This meant the loader box was misaligned, because it still expected the search input to expand. To fix this misalignment, add the margin-left and width styles that apply to the search input to the loader box as well. Bug: T321009 Bug: T317902 Change-Id: Ic177b4cf56cb0a94850037a30db3001777dc52d2
