Description
Having a file like simple_addition.m
1 + 1
gives as expected
julia> mat"simple_addition"
2.0
However, modifying simple_addition.m to
1 + 2
still gives
julia> mat"simple_addition"
2.0
Restarting julia doesn't help.
After showing the msession, running the file, and then hiding the msession, mat"simple_addition" begins to work.
Perhaps I am missing something, seems like someone else should have run into this before :)
Tried on Matlab R2021b on Windows, Julia 1.9.3

Research direction
Reproduce the behavior with simple_addition.m and the mat"simple_addition" call using the reported Julia and MATLAB versions. Compare execution before and after showing and hiding the msession, then trace the MATLAB Engine integration path involved in file evaluation. Done means edits to the .m file are reflected without restarting Julia or toggling the msession.
