Shouldn't this still be const?

It’d do no harm to mark it const, but not much good either. This is a function with side effects, so it’s not like we are just asking the Node a question. It’s not easy to answer the question of what you should and should not do with a const Node. But a side effect of a style update, which can do things like trigger loads, does not seem to be a “const” kind of thing to me.

This caused an assertion failure in svg/custom/bug79798.html: http://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=svg%2Fcustom%2Fbug79798.html
Seems like it is causing us to leave layout with dirty layout.
