I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">musical drama</span>' is the definition.<br/ ><span class="explanation-format__explanation">(an opera is a drama performed in music)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for opera that I've seen before include "Lohengrin, say" , "Patience, for example" , "One with soap perhaps" , "Stage entertainment" , "Drama or comedy set to music" .)
