Tells a producer, once, that a layer's selectors did not do what it meant.
A layer whose selectors resolve to nothing still announces every point and
sounds every value; it only loses the outline a sighted or low-vision reader
follows. That is invisible to anyone who only listens, and was invisible to
every producer through the 4.x contract changes (#750, #991, #1135), which
is how a regression in r-maidr and py-maidr lasted weeks. The console is
where a producer's author will look, so the loss is said there.
A warning rather than an error: the rest of the figure still works, and the
layer is still usable without its highlight.
