Missing css classes in AccordianReferences

[aocenas]

Requirement - what kind of business use case are you trying to solve?

Problem - what in Jaeger blocks you from solving the requirement?

Classes for AccordianReferences are defined in the component but there is no associated css that I could find

jaeger-ui/packages/jaeger-ui/src/components/TracePage/TraceTimelineViewer/SpanDetail/AccordianReferences.tsx

Line 99 in 24a3759

className={cx('AccordianReferences--header', 'AccordianReferences--header', {

. Wanted to check if this is a bug and there should be some css, or the classes in component can be deleted or this is just a convention that components have classNames even if no css is actually needed.

I stumbled upon this as part of work on #509

Proposal - what do you suggest to solve the problem or improve the existing situation?

Any open questions to address

@aocenas Definitely not the convention to have unused classnames. If I had to guess, it probably resulted from the copy pasting mentioned in #498. Go ahead and remove the unused classnames.
