Akihiko Odaki a07cfee644 Extract columns area from UI component (#6650)
UI component used to toggle isComposing state by directly manipulating the
DOM element to avoid the expensive rendering.

However, it is hacky, and is not effective for other states. Instead,
this change makes the rendering cheaper by extracting the huge columns
area.
