Doxygen rendering incorrectly for enum ns3::Timer::State
The Doxygen for ns3::Timer::State renders incorrectly. The source code seems correct.
This could be an upstream bug; I tried upgrading the Doxygen to version 1.8.20 (the latest in that release series) but it didn't change the rendering. I didn't see any reports of enum problems upstream. I haven't found any other enums rendering like this in our codebase (but haven't done an exhaustive check).
