Heatmap rectangles get extended along the x-axis

[carlosdavila91]

Hi,

I think I've detected an unexpected behavior.

When I try to create a Heatmap using ggplotly(), the rectangles in the plot get extended along the x-axis when they shouldn't. See the reproducible example below.

library(ggplot2)
library(plotly)

date_range <- seq.POSIXt(as.POSIXct("2022-07-01 17:33:00"), 
                         as.POSIXct("2022-07-10 17:33:00"),
                         by = "1 day")

set.seed(1)
data <- data.frame(
  x = date_range,
  y = rep(letters[1:5], 2),
  z = runif(10, 1, 8),
  g = sample(LETTERS[1:2], 10, replace = T)
)

p <- data %>% 
  ggplot(aes(x, y)) +
  geom_raster(aes(fill = z)) + 
  facet_wrap(~ g, nrow = 2, scales = "free_y")

p

The result from ggplot, as it is expected to be:

However, plotly results as you see below.

ggplotly(p)
