…s for frame treese in script tasks. This underreports by a significant amount, since only Document, Window and CharacterData (ie. text) nodes are fully represented. That being said, every HTML element in the tree is measured, but only counted as a Node. It's easy to improve this, it just requires adding the appropriate HeapSizeOf derives and increasing the granularity of `measure_memory_for_eventtarget`. google.com shows a dom-tree value of 0.24 MB for me at the moment. r? @nnethercote Source-Repo: https://github.com/servo/servo Source-Revision: 84e25befdd97cf74fb00707dbe150d59d980e977
