Errorbar caps following markershape problematic

[BeastyBlacksmith]

Copying from Slack:

If I try to choose the marker of a scatter plot with markershape=:foo, then this also changes the marker shape of my error bars, which is super undesirable. Is there a way in Plots.jl to just change the shape of the scatter plot’s points’ marks?

MWE1:

julia> using Plots, PGFPlotsX; pgfplotsx()
julia> using Measurements
julia> scatter(title="Foo")
julia> scatter!([(1.0±0.2, 0.9±0.12), (2.2±0.3, 1.8±0.2)]; markershape=:x)

MWE2:

using Plots; plot(1:10,1:10,yerr=0.5,shape=:o)

As expected in Plots 1.32.0, unexpected in 1.35.5 due to the merge of #4362

Me:

plotting MWE2 seperately would look like this
plot(1:10,1:10, shape=:o); yerror!(1:10, 1:10, yerror=0.5, color=1, z_order=:back)
The measurements recipe is another story..

Possible fixes:

1. Measurements fixes the markershapes to the former defaults
2. Remove ability to customize errorcaps
3. introduce new attributes for error markershapes (I tried to argue against something similar in Add option for error bar styles #4360, but thats not necessarily my last word)
