I am using modified @manipulate example from [Tutorial · Interact](https://juliagizmos.github.io/Interact.jl/latest/tutorial/)  
and got `LoadError: value not writable for any mimetypes`.  
If I replace line `Makie.plot(x,y)` with `print(y)` then code is working. Makie.plot() function is working if run outside @manipulate. (Julia v1.2)  
What could cause that?

```julia
using Makie
import Blink, Interact
function run_all()
    x = y = 0:0.1:30

    freqs = OrderedDict(zip(["pi/4", "π/2", "3π/4", "π"], [π / 4, π / 2, 3π / 4, π]))

    s = Makie.plot(rand(5))
    display(s)
    mp = Interact.@manipulate for freq1 in freqs, freq2 in Interact.slider(0.01:0.1:4π; label = "freq2")
        y = @. sin(freq1 * x) * sin(freq2 * x)
        Makie.plot(x,y)
    end
    w = Blink.Window()
    Blink.body!(w, mp)
end
run_all()

```

Dear Kestusis,

i have the same problem, i cannot render a Makie plot in Blink window…  
Were you able to solve the issue?

Thank you.  
Best Regards.  
Olivier.
