barplot with Observable colors is broken #617

Looks like something weird is going on with GeometryBasics. Consider the following (stacktraces truncated): julia> cs = Observable(to_colormap(:viridis, 4))
julia> sc = barplot(rand(Point2f0, 4), color=cs)
julia> cs[] = to_colormap(:viridis, 4)
ERROR: Metadata array needs to have same length as data.

It looks like at each call another 16 are added. Not sure if it's relevant. |

@asinghvi17 sorry to invade the issue for something off-topic, but how did you get this nice presentation of stacktraces? |
|
See https://github.com/jkrumbiegel/ClearStacktrace.jl (This may also be of interest JuliaLang/julia#36026) |
|
Hmm...16 is 4x4, 4 vertices per bar x 4 bars. |

Fixed in: JuliaPlots/AbstractPlotting.jl#444 |

MWE
If I replace
barplotwithscatter, it works.The error is
Verision info
I can also reproduce it with an older julia version
