Setting breakpoint on function with kwargs causes break on every kwcall

[fredrikekre]

kw1(x; a=1, b=2) = kw2(; a=a, b=b)
kw2(; a=1, b=2) = a + b
function main()
    x = rand(3) # dummy call
    return kw1(x)
end

julia> @enter main()
In main() at REPL[2]:1
 1  function main()
>2      x = rand(3) # dummy call
 3      return kw1(x)
 4  end

About to run: (rand)(3)

Edit: Happens on both Julia 1.9.0-beta4 and master (even though the breakpoint looks slightly different), but not in Julia 1.8.5.

On 1.9:

julia> Core.kwfunc(kw1)
kwcall (generic function with 1514 methods)

On 1.8

julia> Core.kwfunc(kw1)
kw1##kw (generic function with 1 method)

This interacts badly with https://github.com/JuliaDebug/JuliaInterpreter.jl/pull/528.

I think I ran into this today; it's quite debilitating when trying to debug things in the DataFrames universe. Is there any reasonable workaround?
