Hover text not visible for small bars

I can't find a way to get the hover text to show up in a bar chart when the value of the bar is 0 or very small. The bar is not shown at all when the value is 0 but you can get around that by adding an outline color which makes it visible. However, the hover text does not show. One work around is to replace the zero with a small number but this does not show the hover text unless you zoom in or move the cursor extremely slowly. Another work around which works okay is to add a very small point geom which will provide the hover text for the small bar but then there are two different hover text sources for the larger bars which looks strange.

An ideal solution in my opinion would show a line when the value is 0 and the hover text would show up over the line. This is not the default for ggplot though so it would also be fine if when the line is added by including an outline for the bar geom the hovertext showed up when hovering near the line.

library(ggplot2)
library(plotly)

df <- data.frame(x = letters[1:5], y = 0:4*10, text = paste("some text", 1:5))

# No bar in ggplot or plotly
gp <- ggplot(df, aes(x, y, text = text))+
  geom_col()

ggplotly(gp, tooltip = "text")

# has line but no hovertext
gp <- ggplot(df, aes(x, y, text = text))+
  geom_col(color = "black")

ggplotly(gp, tooltip = "text")

# has small bar but can only see hover text if zoom in
df$y[1] <- 0.01

gp <- ggplot(df, aes(x, y, text = text))+
  geom_col(color = "black")

ggplotly(gp, tooltip = "text")

# Hover text shows up for point but mutiple hovertexts for larger bars
gp <- ggplot(df, aes(x, y, text = text))+
  geom_col(color = "black")+
  geom_point(size = 0.1)

ggplotly(gp, tooltip = "text")

Beginne damit, die ggplotly-Beispiele im Issue auszuführen und nachzuverfolgen, wie geom_col-Balken Hover-Ziele für null und sehr kleine Werte erzeugen. Identifiziere die Hover-Behandlung von Balken und die zugehörigen Tests und überprüfe anschließend, dass Balken mit dem Wert null oder sehr kleinen Werten den angeforderten Tooltip anzeigen, ohne doppelte Hover-Quellen zu erzeugen.
