Changed scrollview-list to listen for render, instead of renderUI, and invoke syncUI once it's done applying it's classes. The call to render calls syncUI, and establishes a 'vert'/'horiz' class marker, which scrollview-list keys off of, to add padding etc. This changes the dimensions again, and hence the need to call syncUI again. Fixes #2531122 NOTE: Removed workaround from src/common/tests/manual/skins.html. Shouldn't be required after this fix is in.
