Hover info/tooltip is using y labels and not values which causes problems with boxplots hoverinfo

When you use your own labels for values on x or y axis then hoverinfo/tooltip will show these labels. This is generally ok but it is problem for boxplots, where you cannot change hoverinfo text. For example, you want to make boxplot of some time values (in minutes) but you want to format labels on y axis to HH:MM. If some value of a quartile hit the value displayed on y axis, the hover info will show HH:MM label for this value while for other values it will show just time in minutes... See the hoverinfo for the first and the third quartile compared to other values on the figure bellow. Any suggestion how to fix it or make it consistent so the formatting is the same? Thank you!

library(ggplot2)
library(plotly)

p<-ggplot()+
  geom_boxplot(aes(x="A", y=c(5,15,25,25,45,72)))+
  scale_y_continuous(breaks=seq(0, 75,15), labels=c("00:00","00:15","00:30","00:45","01:00","01:15"))+
  ylab("") 

ggplotly(p)

ggplot2 と plotly を使用し、ggplotly(p) で例を再現してから、scale_y_continuous がカスタムラベルを指定した場合に boxplot のホバー情報がどのように生成されるかを調べます。ラベル付きの目盛りに一致する四分位値とその他の値を比較し、生成される tooltip の書式がすべての boxplot 値で一貫していることを確認します。
