Interact.jl + Mux.jl + Plots.jl dynamic updating plots memory leak

question
plotting
#1

with scripts running in background, i open a browser and see the plot updating, after i close the browser window, memory starts increasing.
gc’s not work(see the code)

the following shows the problem with Blink(electron) …

after I close the electron window … electron.exe occurs and the memory keeps going up

when i close the windows i noticed that one process of electron.exe exits at the same time
maybe communication down between electron and the prog
