Can anybody point me to code that gets run when accessing a property on a DOM node in OSS rendering engines?
Also depends on whether the property getter is marked side-effect-free and whether there are CSE/LICM opportunities.

And whether the property is annotated as "cached" in which case the JIT can read the cache directly without doing a vmcall.

Given opportunity to store truth in user JS and read from that instead of DOM, would you? Eg, option.selected.
