somewhere in `Bonds.initial_value(x)` relies on `Pair`'s questionable promotion behavior

[adienes]

in JuliaLang/julia#58836, triage desires to remove the promote_rule defined for Pair (and Some) as to make it consistent with every other container type in the language

I am going through the results of the Nanosoldier run so as to avoid as much potential downstream impact as possible.

I noticed that this test is failing

PlutoUI.jl/test/runtests.jl

Line 239 in f6e52f5

@test default(el) isa Vector{Function}

I am not sure precisely where the relevant initial_value method is defined, but I assume it is related to this function. do you think it would be feasible to update this in line with #58836

I looked at it again, and my test is semantically correct. What is your request exactly?

[adienes]

the test relies on the fact that on master Base.vect calls a promote_type method of Pair that really should not exist, so

[cos => "cosine function", sin => "sine function"] is a Vector{Pair{Function, String}}, whereas after the PR it would be a Vector{Pair{A, String} where A

so default(el) goes from a Vector{Function} to a Vector{Pair{A, String} where A}
