OpenAL: Ambient Sounds with maximum distance ocassionally leak memory

After closing the game, both GameMemory.cpp, as well as ASAN report memory leaks on ambient sound events.
Only from Drawable.cpp:4535

Upon investigation by halting in debugSingleBlockReportLeak on AudioEventRTS, an event for sound file "ajddbird.wav" / "Amb_JungleDayDenseAmbientBirds" is leaked.
The event info (m_eventInfo) itself seems to be interestingly enough already destroyed.
