Error when computing jacobian for broadcasted function

使用 Julia 1.10.0-beta2 以及列出的 AbstractDifferentiation 和 Diffractor 版本重现三个 jacobian 调用。从 src/stage1/broadcast.jl:27 以及 src/tangent.jl:351 和 :375 处的 createinstance/rebundle 路径开始，然后比较正常工作和失败的 broadcast 案例。逐元素 broadcast 的 sin 表达式能够计算其 jacobian，且不再出现报告的 TangentBundle MethodError，即表示完成。

Simple broadcasting errors for me. See below.
I am on Julia 1.10.0-beta2+0.x64.linux.gnu

within the following environment:

Status ~/.julia/environments/v1.10/Project.toml
[c29ec348] AbstractDifferentiation v0.5.2
[9f5e2b26] Diffractor v0.2.1
[31c24e10] Distributions v0.25.100

This shows the issue (verified that I get the same problem with gradient from AbstractDifferentiation.jl):

using Diffractor: DiffractorForwardBackend
using AbstractDifferentiation: derivative, jacobian
jacobian(DiffractorForwardBackend(), θ -> sin(θ[1]) + sin(θ[2]), [0.3, 0.8])  #  works
jacobian(DiffractorForwardBackend(), θ -> sum(sin, θ), [0.3, 0.8])                # works
jacobian(DiffractorForwardBackend(), θ -> sum(sin.(θ)), [0.3, 0.8])               # errors

last command errors with (truncated error):
