Details

This is based on bug 151620 comment 52 and bug 151620 comment 53. In order to cover bug 151620 comment 24, we could use "strict" line-heights on inline items only if there were #text nodes present in the containing block. Otherwise we would use the quirks-type calculation. This way if you had text, you'd presumably want the line-height to match that and use strict rendering, but if you did not have text, then you would not gain the seemingly magical (to anybody not familiar with the issues) line-height and it would work like it has in the past. Also, if a line-height was explicitly applied, it would be honored instead of following the above formula. (So we don't get another bug like bug 152959). It would only be the inherited line-height's that would go through this "filter." The benefits over bug 22274's resolution would be that most (if not all) pages should work (and it would cover <div>s too), and the benefit over bug 151620's resolution would be that we could still get the strict rendering in <td> elements. Work on this should completely replace the patches for bug 151620 and bug 152979 and bug 152959 (if one is made). This is the logic that should be used especially if bug 153032 is implemented.

Why would those tests fail? "Also, if a line-height was explicitly applied, it would be honored instead of following the above formula." Those tests have line-height defined for the containing elements.
This suggestion would still cause the following testcases to fail: http://www.hixie.ch/tests/adhoc/css/box/inline/010.xml http://www.hixie.ch/tests/adhoc/css/box/inline/010.html (And anyway, per CSS, you can't tell the difference between a property that is present in an author stylesheet and one that is not -- all properties are always set, even if merely by inheritance, or by the UA stylesheet, or whatever. That really shouldn't change, not even in quirks mode.)

This is hard to implement and makes no sense in the CSS model. ->WONTFIX
