The main window DOM influences window opening and startup times, and currently includes a lot of stuff that could be loaded lazily. The aim of adding performance metrics for the DOM size is (a) to be able to verify fixes and (b) to be able to catch regressions if people add an excessive amount of new DOM that could be loaded as-needed instead of hardcoded in the DOM.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.
