Not all facets being shown with facet_wrap, boxplot and ggplotly

@cpsievert I'm seeing several open issues that are similar to this one (#1132, #1962, #1301, #1254, #1243, #1099, #1086, #897) and wasn't sure whether to add a new issue or not.

It seems like perhaps plotly is having some trouble with facet_wrap() -- my reprex is pretty simple. On my machine using the development (and non-development) version of plotly some facets are not being shown.

The images below are from plotly 4.9.4.9000.

library(ggplot2)
p <- ggplot(mtcars, aes(y = mpg)) + geom_boxplot() + facet_wrap(~cyl)
plotly::ggplotly(p)

Just ggplot2 (no plotly)

ggplotly (missing a couple of boxes)

まず、ggplot2 の facet_wrap() と plotly::ggplotly() を使って R reprex を実行し、レンダリングされたファセットを提供されたスクリーンショットと比較します。元の ggplot2 プロットで生成されたすべてのファセットボックスが ggplotly に表示されれば、作業は完了です。
