`sets()` recognised `name:` and `name =>` and not `name(arg) =>`, which is how
Slint writes a callback handler with a parameter. There is exactly one of those
among the properties asserted — `accessible-action-set-value`, the action a
screen reader uses to type a number into a slider — so the test reported
`SliderTrack` as missing the action it declares four lines above.
A false alarm rather than a false pass, and the less dangerous of the two. It
is still worth fixing rather than dropping the assertion: set-value is the
action that makes a slider reachable without dragging, which is most of what
the actions were added for.
