Description

It seems that dynamicTicks=TRUE in ggplotly is working for categorical data only when the plot is not faceted. Is there a reason for that or is this part of the bug you were working on here: https://github.com/ropensci/plotly/issues/860?

library("ggplot2")
library("plotly")

p1 <- ggplot(mtcars) + 
  geom_line(aes(x=as.factor(hp), y=mpg, group=1))


p2 <- ggplot(mtcars) + 
      geom_line(aes(x=as.factor(hp), y=mpg, group=1)) +
      facet_wrap(vars(gear))

#non faceted plot works
ggplotly(p1, dynamicTicks = TRUE)

#faceted plot does not work
ggplotly(p2, dynamicTicks = TRUE)

Research direction

Run the provided R examples for ggplotly() with dynamicTicks=TRUE, comparing the non-faceted p1 with the facet_wrap() version p2. Trace the dynamicTicks and facet_wrap handling from this entry point; done means categorical axes use dynamic ticks consistently in the faceted plot as they do in the non-faceted plot.
