On edit-button simply set position to top.
Made this change directly in template since edit-button
is only used in one place.
Had to wrap the comments toggle button in span tag to make
tooltip show even when disabled as per bootstrap-vue docs.

Note: Also changexc button to gl-buttonto be consistent
with rest of file.
