Description
Description of the issue
When I try to display any given number of barpolar plots using the subplot() function, plotly only shows one plot that has somehow aggregated all of the data from the individual plots.
Minimal reprex
Code
library(plotly)
# First barpolar plot
plot1 <- plot_ly(type = 'barpolar') %>%
add_trace(
r = c(10, 15, 20, 25, 30),
theta = c("A", "B", "C", "D", "E"),
marker = list(color = c("red", "blue", "green", "purple", "orange")),
name = "Plot 1"
) %>%
layout(title = "Barpolar Plot 1")
# Second barpolar plot
plot2 <- plot_ly(type = 'barpolar') %>%
add_trace(
r = c(5, 10, 15, 20, 25),
theta = c("A", "B", "C", "D", "E"),
marker = list(color = c("cyan", "magenta", "yellow", "gray", "pink")),
name = "Plot 2"
) %>%
layout(title = "Barpolar Plot 2")
# Combine the two plots into a subplot
subplot(plot1, plot2, nrows = 1)
Result
Expected result
Both plots shown individually, in a grid with 1 column and 2 rows.

Research direction
Start with the supplied R reprex and trace how subplot() combines the two barpolar plotly objects. Compare the generated subplot layout and trace assignments for barpolar plots, then run the reprex to verify that each input remains in its own grid cell rather than being aggregated.
