Description
It's not currently possible to compute
d1 ≈ d2
for all differentials d1 and d2. Probably we want to be able to do this, and it shouldn't be too hard.

Research direction
The issue names no files or tests. Start by locating the differential type definitions and existing approximate-equality behavior in ChainRulesCore.jl, then trace how d1 ≈ d2 is dispatched. Done means approximate equality works for all differential pairs described by the issue, with tests covering the supported variants.
