This is weird. Seems to only occur in Juno at the Julia REPL, not when Julia REPL is run at the command line.

```julia
struct A
    a::Float64
    b::Int
    c::Float64
end

julia> a = A(9, 6, 1.5)

```

Then repeatedly print `a`.

Sporadically, the displayed text will change between `A(9.0, 6, 1.5)` and `A(9.0, 6, 1.2)`.

`a.c` always prints the correct value.

What’s going on here?

This is happening because of  
[https://github.com/JuliaLang/julia/issues/29885](https://github.com/JuliaLang/julia/issues/29885)

As far as I can tell closing the workspace pane circumvents that bug because the race condition isn’t being triggered.
