clang-format produced code that (choose all that apply): 
- Doesn't match Chromium style
- Riles my finely honed stylistic dander
- No sane human would ever choose

Here's the code before formatting:

/**
 * FeedbackReporter enables Chrome to send feedback to the feedback server.
 */
public interface FeedbackReporter {
    /**
     * Report feedback to the feedback server.
     *
     * @param collector the {@link FeedbackCollector} to use for extra data.
     */
    default void reportFeedback(FeedbackCollector collector) {}
}

Here's the code after formatting:

/**
 * FeedbackReporter enables Chrome to send feedback to the feedback server.
 */
public interface FeedbackReporter {
    /**
     * Report feedback to the feedback server.
     *
     * @param collector the {@link FeedbackCollector} to use for extra data.
     */
    default void
        reportFeedback(FeedbackCollector collector) {}
}


Here's how it ought to look:

/**
 * FeedbackReporter enables Chrome to send feedback to the feedback server.
 */
public interface FeedbackReporter {
    /**
     * Report feedback to the feedback server.
     *
     * @param collector the {@link FeedbackCollector} to use for extra data.
     */
    default void reportFeedback(FeedbackCollector collector) {}
}
