Description

Hi.

Firstly, thanks for this amazing library.

I believe there is a problem plotting histograms using the interactive 'view' mode.

library(tmap)
data("World")

map <- tm_shape(World) + 
  tm_polygons(col="pop_est", legend.hist = T)

tmap_mode("plot")
map # <<< WORKS

tmap_mode("view")
map # <<< DOES NOT WORK

Is there a workaround/fix planned for this please?

Thanks.

Research direction

Run the provided World/tmap example in both plot and view modes, using the legend.hist option on tm_polygons. Compare the working plot output with view mode and trace the histogram rendering path. Done means the same histogram legend renders correctly in interactive view mode.
