Issue:
Plotting into an existing axis throws on v0.20.0
- [x] are you running newest version (version from docs) ?
- [x] can you reproduce the bug with a fresh environment ? (`]activate --temp; add Makie`)
- [x] What platform + GPU are you on? **Ubuntu 22.0.4, Nvidia**

Hello, thank you for all the hard work on Makie! After updating to latest, plotting into an existing axis throws. 

```
julia> using GLMakie

julia> let 
           fig = Figure()
           ax = Axis(fig[1, 1])
           plot!(ax, [10, 15, 20])
       end

Pull request description:
* fixes for GeoMakie (using  `@Block` outside of Makie)
* closes https://github.com/MakieOrg/Makie.jl/issues/3399
* allows `onany(f, scene, args...; update=true)`
