Whenever we do this, Rollup needs to materialize this as an object.
This causes it to also add the Babel compatibility property which is
unnecessary bloat. However, since when we use these, we leak the object
this often also deopts any compiler optimizations.
If we really need an object we should export default an object.
Currently there is an exception for DOMTopLevelEventTypes since
listing out the imports is a PITA and it doesn't escape so it should
get properly inlined. We should probably move to a different pattern
to avoid this for consistency though.
We need a different "component tree" thingy for Fabric.
A lot of this doesn't really make much sense in a persistent world but
currently we can't dispatch events to memoizedProps on a Fiber since
they're pooled. Also, it's unclear what the semantics should be when we
dispatch an event that happened when the old props were in effect but now
we have new props already.
This implementation tries to use the last committed props but also fails
at that because we don't have a commit hook in the persistent mode.
However, at least it doesn't crash when dispatching. :)
