Fix css:false with hooks with no explicit done callback

Editor assessment

fix(transition) says css false with hooks that have no explicit done callback was fixed, naming a precise configuration. The scope and type fit, the header is imperative and unterminated, and the body closes issue #1149 in valid footer form. No body explains the resulting bug or the fix's approach, so the why is thin, but the subject delineates the case well. Clear and correctly classified, it is publishable with a modest rationale omission.
