This test <https://trac.webkit.org/browser/trunk/LayoutTests/js/dom/domjit-function-get-element-by-id.html> started failing after this patch <>. See https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=js%2Fdom%2Fdomjit-function-get-element-by-id.html Saam suggested calling flattenDictionaryObject should fix this, and it seems to work.

This was also a 7% progression on the "Dromaeo CSS Selector" test.
