ggplotly tool tip disappearing for some points

[wdm0336]

Developing a Shiny app in R3.6.3 with ggplotly version4.9.2.

Plotting a scatter plot from ggplotly with tooltip of each point.

As the tool tip for each point grows larger (more rows), the points toward the top of the graph lose the tooltip even if the tool tip is the same for each point.

If the tooltip is the same, why do some points lose the tool tip and others can display it?

In the code below vary numRows or the size of the plot and points from top towards the bottom lose the tooltip.

numRows = 20

ggiris <- ggplot(data = iris,
                 aes(x = Petal.Width,
                     y = Sepal.Length,
                     color = Species,
                     text = paste(rep(LETTERS, length.out = numRows), collapse = "<br>"))) +
  geom_point()

ggplotly(ggiris, tooltip = "text")

This is what I see with the development version of plotly, which seems to be correct. If you're seeing something different, perhaps try upgrading (remotes::install_github("ropensci/plotly")) and/or increasing the height of the plot?
