While working on https://bugs.webkit.org/show_bug.cgi?id=147192, I realized that there's no easy way to test the fact that search fields should be empty (no placeholder text) by default besides using pixel tests, which are not particularly useful. This could be addressed via an internal API that renders DOM elements or part of the DOM onto a canvas element in the DOM, so that we can run tests regarding the look of elements in Javascript, without using pixel tests.
