hovertemplate not rendering text for single items in the plot

When using hovertemplate in bar charts to annotate bars,
if the variable is present only once then text annotation doesn't work

For example in below image, Type B is only present once
and when hovered on it shows as "%{text}

but when using hoverinfo it seems to work fine

I need to use hovertemplate, as i had to use it in a function, where color and text options are passed as variable

any workaround to fix this?

Reproducible code example

library(data.table)
library(plotly)

data <- data.table(Date = c(rep(as.Date("2022-10-18"), 3),
                                rep(as.Date("2022-10-19"), 3),
                                rep(as.Date("2022-10-20"), 3)),
                       Type = c('A', 'B', 'C', 'A', 'D', 'C', 'C', 'D', 'A'),
                       Frequency = c(6, 3,  6, 10,  9,  9,  9,  3,  2))

# hovertemplate - Type B is only one entry and it shows as %{text}
plot_ly(data, x=~Date, y=~Frequency, color=~Type, type='bar', text=~Type,
        hovertemplate=paste('<b>%{text}</b>',
                            '<br><b>%{y}</b>',
                            '<br><b>%{x}</b>',
                            '<extra></extra>')) %>%
  layout(barmode="stack")

# hoverinfo - works as expected
plot_ly(data, x=~Date, y=~Frequency, color=~Type, type='bar',
        hoverinfo = 'text',
        text = ~paste('<b>', Type, '</b>',
                      '<br><b>', Date, '</b>',
                      '<br><b>', Frequency, '</b>')) %>%
  layout(barmode="stack")

Führen Sie das reproduzierbare R-Beispiel aus dem Issue aus und vergleichen Sie die Ausgaben von hovertemplate und hoverinfo, wobei der Fokus auf dem einzelnen Type B-Balken liegt. Verfolgen Sie den vom R-Paket verwendeten Plotly-Renderingpfad; abgeschlossen, wenn hovertemplate den Type B-Text anstelle des Literals %{text} anzeigt.
