Note this actually changes the "subtle" color to be darker. As far
as I understand this is an intentional decision. The old color token
from OOUI is deprecated and intentionally made darker in Codex.
See Ie667c35 and most notably T313502.

I believe this was a mistake in the previous patch Idd57997. Using
only the .text() of the parent reference is not sufficient. Think of
a reference that contains a <math> formula or – even worse – is
nothing but a <math> formula. The preview will be empty in this case.
Click handlers in the preview need to be disabled. It's only a
preview.
