ProfileView warntype_last() throws error

General Usage
1

In Julia 1.11, looking to understand sources of type instability, I profile my code:

...  # "diffed_residual", and some variables defined here by a large code base: 
     # no MVE
using ProfileView
using Profile

out = diffed_residual(beam; X,U=(SVector{0,𝕣}(),),A,t,SP)
Profile.clear()
Profile.@profile for i=1:30000
    local out = diffed_residual(beam; X,U=(SVector{0,𝕣}(),),A,t,SP)
end
ProfileView.view(fontsize=30);

I get a good flamegraph, with some red color (type instability) I want to know more about. I can click on some functions and in the REPL type warntype_last() and obtain type-inferred code: perfect.

But clicking on other functions in the same flamegraph, then invoking warntype_last() I get

julia> C:\Users\philippem\.julia\dev\Muscade\src\Taylor.jl:181, MethodInstance for apply{:compose}(::var"#439#440"{:compose, EulerBeam3D{BeamCrossSection, false}}, ::SVector{6, ∂ℝ{2, 12, ∂ℝ{1, 12, Float64}}})

This is distinct from the (understandable) error one gets when clicking on an inlined function.

Is this maybe a known bug of ProfileView.jl? Or did I miss something?
