This is a followup bug (after Bug 256850) to fix the test /fast/table/border-changes.html Firefox passes all the tests on that file. Safari and Chrome fails FAIL getComputedStyle(cell, '').borderLeftStyle should be inset. Was solid. FAIL getComputedStyle(cell, '').borderRightStyle should be inset. Was solid. FAIL getComputedStyle(cell, '').borderTopStyle should be inset. Was solid. FAIL getComputedStyle(cell, '').borderBottomStyle should be inset. Was solid. FAIL getComputedStyle(cell, '').borderTopWidth should be 0px. Was 1px. FAIL getComputedStyle(cell, '').borderBottomWidth should be 0px. Was 1px. FAIL getComputedStyle(cell, '').borderTopStyle should be none. Was solid. FAIL getComputedStyle(cell, '').borderBottomStyle should be none. Was solid. The fix should not be too hard. I had partially done it, but I wanted to make sure to isolate the fixes. It probably requires a specific WPT test case for it.
