Remove redundant check in updateChildren

[dy]

This check is handled by more generic following condition.

[goto-bus-stop]

Hmm, I think this might be a performance optimization to avoid having to walk through all the children in the common case? Most of the time your tree keeps a similar shape, and an update doesn't move elements around, so it avoids calling same() for every sibling element then. I don't know what the actual impact is though.

Not sure initializing a loop is perf hit - condition check looks like the cheapest thing possible. I'd speculate this clause is kept as part of the mindflow, without realizing the generalized case. Also it's a bit easier to understand the way it is now. But there doesn't seem to be any optimization, just a couple ifs and break. In fact that adds some bytes to bundle.
