Issue with log scale displaying floating point numbers when on x axis.

The log scale should display rounded integers, but is displaying floating points with many decimal places. Seems to be fine though when the log scale is on the y axis. Also does not happen all the time. Works for another graph I have.

Brief description of the problem

library(plotly)
library(tibble)


# fake data
df <- tibble(geog_area = letters[1:10],
             value = runif(10, 100, 100000))

plot_ly() %>%
  add_trace(data = df,
            x = ~value,
            y = ~geog_area,
            type = 'bar',
            hovertemplate = paste("%{x:,.0f}")) %>%
  layout(xaxis = list(tickformat = ",",
                      type = "log"),
         yaxis = list(title = "",
                      autorange = "reversed"),
         barmode = 'stack',
         hovermode = 'y unified') %>%
  hide_legend()

Start by running the supplied R example with plotly 4.9.4.1 and compare x-axis log tick formatting with the y-axis case. Trace the log-axis and tickformat handling in the relevant plotly.R and JavaScript paths; done means reproducible x-axis log charts display rounded integer ticks without regressing y-axis behavior.
