Description

If I try to debug a function that I'm also timing using TimerOutputs, only lowered code is displayed, and I cannot step normally through the function.

MWE:

julia> using TimerOutputs

julia> using Debugger

julia> my_timer = TimerOutput()
────────────────────────────────────────────────────────────────────
                           Time                    Allocations      
                  ───────────────────────   ────────────────────────
Tot / % measured:     91.5ms /   0.0%           4.68MiB /   0.0%

julia> @timeit my_timer foo() = begin
       println("hello")
       end
foo (generic function with 1 method)

julia> @enter foo()

This using Julia-1.11.3, Debugger-0.7.10 and TimerOutputs-0.5.27.

Obvious workaround is to take out the timing while I'm debugging, but that's not ideal especially in a bigger code where there might be many timed functions.

Research direction

Start by reproducing the provided MWE with Julia 1.11.3, Debugger 0.7.10, and TimerOutputs 0.5.27, using @timeit and @enter. Inspect how Debugger handles the timed function and its lowered display. Done means stepping through the original function source works normally while timing remains enabled.
