Description

When using scrollZoom together with nticks, the plot gets stuck when trying to zoom around.

A few scrolls are working, then the plot gets stuck, That also hapens, when zooming in first.

library(plotly)

df <- data.frame(
  ts = seq(as.POSIXct("2019-03-20 00:00:00"), by = "hour", length.out = 24),
  val = sample(1:100, 24)
)

plot_ly() %>% 
  add_bars(data = df, x = ~ts, y = ~val) %>% 
  layout(dragmode = "select", autosize = TRUE,
         bargap = 0.05,
         xaxis = list(type = "date",
                      nticks = 24,
                      tickmode = "auto"
         )) %>% 
  config(scrollZoom = TRUE)

Research direction

Start by running the R reproduction with plotly, scrollZoom, and nticks set to 24, then inspect the zoom and axis tick handling involved in the generated plot. Done means repeated scrolling continues to zoom or pan normally instead of becoming stuck; the issue names no files or tests to target.
