Devoncarew fix search

Hey Yegor, looks like your last CL had a stray html import in it. It was causing a build failure: https://drone.io/github.com/dart-lang/spark/1163.

You'll probably want to change to either:
- making pull requests off a branch of the spark repo, or
- adding drone.io coverage for your fork of spark

so that you know that your CLs will build through clean. Thanks!

(TBR'ing to unbreak the build)
