Previously I had added strong typing for
addEventListener
for theViewerElement
's custom events, but I forgot to do the same forremoveEventListener
. In this PR, I am addingremoveEventListener
, but I'm also moving this to be type only. Previously I did this typing by overriding the baseaddEventListener
and calling it onsuper
, but there is nothing actually needed at runtime for this, so we may as well remove any runtime impact (one extra frame on the callstack, a tiny bit of extra code in the final bundle).
