Buggy findfirst(p::Union{Fix2{typeof(==),T}, Fix2{typeof(isequal),T}}, r::StepRange{T,S}) where {T, S}?

What is the interpretation of the following two executions?

julia> findfirst(==(-7), 1:-1:-10)

julia> findfirst(==(-7), collect(1:-1:-10))
9

This is wrong too:

julia> findfirst(==(2),1:-1:2)
