Submitted test on various input and button elements and vertical-lr writing mode: http://test.csswg.org/suites/css-writing-modes-3_dev/nightly-unstable/html/form-controls-vlr-005.htm Note that a) the test uses a "SHOULD": so passing that test is recommended but not required to be able to claim conformance with the spec. b) the tests in all CSS test suites never use vendor prefixes
