Description
ggplot2 has the dir option that allows facets to be filled by columns, rather than rows. However, it does not display properly in plotly.
library(ggplot2)
library(plotly)
data <- data.frame(
x = seq(1:100),
y = sample(1:1000, 100),
z = factor(sample(1:4, 100, replace = T))
)
plot <- ggplot(data, aes(x, y)) +
facet_wrap(~ z, dir = "v") +
geom_point()
plot
ggplotly(plot)
ggplot works properly and fills the facets from top to bottom, left to right.
Using the current dev version of plotly, ggplotly doesn't display all the facets, and still orders them from left to right, top to bottom.

Research direction
Start by running the issue's R example with facet_wrap(~ z, dir = "v") and ggplotly(plot), then trace how ggplotly converts the facet layout and ordering. Compare the result with ggplot's top-to-bottom, left-to-right layout; done means all facets display in the requested vertical order.
