Inline areas have their own line-height trait which can be different to
the line-height on the containing line area / containing block.
line-height when specified on an inline fo has a different meaning,
i.e. the inline area returned MUST have the exact line-height as
specified, while line-height on a block level sets the minimum height
for all decendant inline areas. We don't do any of that in the moment.
Side note: in layout we don't know any more if a property is inherited
or specified on that element, that could be a complication here. Finn,
any thoughts on this?
You mean the phrases: "If the property is set on an inline-level
element, it specifies ..." is only used when the line-height property is
explicitly set on inline-level? If the line-height is inherited then
that paragraph isn't operative?
If that is the case, then line-height is the only(?) property that isn't
using the specified value. Strange. But is it not a big deal, the
inline-level .bind() method will have to check if the line-height is
lineHeightExplicit = pList.getExplicit(PR_LINE_HEIGHT);
which is then non-null is the property is set on the element. However it
is a huge deviation from the rest of the properties.
