If the specified value is "inherit", or is a percentage (in some
properties like line-height) / relative unit (em, rem, ex, ch...), or
the computed depends on other properties (like the computed value for
top in relative positioned elements), then the latter may change with
the same specified value. This should trigger transitions.
That is, answering also to David Hyatt, if I say :root { width: 100% }
I should not have a transition on width when the window is resized,
but if I say :root { width: 100vw; } I should have.
