fix: restore performance for large amount of child nodes#760
Merged
Conversation
as part of #550 ("drop redundant and broken `Element.appendChild` implementation") the `_onUpdateChild` was not passed the added child, so the `childNodes` were re-indexed from the `firstChild` each time a node was appended. Now that the added child is being passed, the performance in 0.9.0 is still not as good as in 0.8.*, but this is because of the higher amount of checks being executed before adding a node. fixes #748

_onUpdateChildwas not passed the added child, so thechildNodeswere "re-indexed" from thefirstChildeach time a node was appended.This is why the performance degraded significantly, when there are a lot of childNodes to be appended.
