Error showing value of type Plots.Plot{Plots.GRBackend}

[sjkobayashi]

With the latest version of julia-snail and julia-snail-multimedia-enable set to t, I get an error when I try to use Plots.plot.

For example, running using Plots; plot(sin, 0, 2π) gives

Error showing value of type Plots.Plot{Plots.GRBackend}:

If julia-snail-multimedia-enable set to nil, the plot works normally by showing a dedicated window.

I'm seeing the same thing with CairoMakie. I'm on Julia 1.8.4.

Sorry about that. Should be fixed in https://github.com/gcv/julia-snail/commit/679498c65157224ec136eb225f019f2612ca5818.

Thank you! It works now.
