Comment (by igt0): Great question, the css2 specification[1] says that the line height factor should be between 1.0 and 1.2. Mozilla uses 1.2 for some time[2] and only if the ascending and descending values are 0. Chrome has its own thing[3]. That said, for the short and medium term, I think the current test makes sense because if the line factor changes, the test will break. I tried to think about a ref test instead of JS test. However the 1.2 value would be hardcoded on it anyway.
