Description

The original function is more flexible:

julia> sortslices(rand(2,2,2); dims=(1,2));

julia> rrule(sortslices, rand(2,2,2); dims=(1,2));
ERROR: TypeError: in keyword argument dims, expected Integer, got a value of type Tuple{Int64, Int64}
Stacktrace:
 [1] top-level scope
   @ REPL[21]:1

Probably easy to widen the rule, needs some care, and tests.

Research direction

Locate the ChainRules rule for sortslices and its existing tests, then inspect how the dims keyword is typed and handled. Add coverage for tuple-valued dimensions and confirm that the rule accepts the same forms as the original function.
