@taion why node check is needed here in onTransitionEnd?
addEndListener check is not enough for this?
Or is here for some historic reasons?
Tests pass if node check is removed from if check.

i think this is a legacy thing from the conversion to use nodeRef; if there's no associated node, then previously it was impossible to call addEndListener, because the first arg was expected to be the node.

Is there any case when node may be missing?

might be possible if e.g. the transition is rendering a child that's actually not there, maybe?

this is not equivalent to the original code. previously, if:
nodewas definedaddEndListenerwas definedtimeoutwas defined
then we would call addEndListener and we would call setTimeout with this.nextCallback.
in this revision, there's no way for both addEndListener and setTimeout to get called

Is this the right behaviour for both of them to call nextCallback?
Does setNextCallback appeared in codebase because of this, to call callback only once?

i think the idea is that, if there's a timeout and an end listener, that the first one that triggers will "win"
…ional Purpose of #464 was to make timeout optional and default to 0 if `addEndListener` prop is missing, but propType was still marked as required Also removed unused class `SimpleSet`
