Remove white contour in legend

[abichat]

When using ggchicklet legend on a non-white backgroud, one can see the white contour around the legend, as below.

Would it be possible to remove the contour? Or better: to choose the contour color? (Maybe with the new key_glyph argument?)

Thanks

library(ggchicklet)
library(hrbrthemes)
library(ggplot2)

data("debates2019")

spkr_ordr <- aggregate(elapsed ~ speaker, data = debates2019, sum)
spkr_ordr <- spkr_ordr[order(spkr_ordr[["elapsed"]]),]

debates2019$speaker <- factor(debates2019$speaker, spkr_ordr$speaker)

ggplot(debates2019) +
  geom_chicklet(
    aes(speaker, elapsed, group = timestamp, fill = topic),
    colour = "#252a32"
  ) +
  scale_y_continuous(expand = c(0, 0.01), position = "right") +
  ggthemes::scale_fill_tableau("Tableau 20") +
  coord_flip() +
  labs(x = NULL, y = "Minutes Spoken", fill = NULL) +
  theme_ft_rc() +
  theme(panel.grid.major.y = element_blank()) +
  theme(legend.position = "bottom")

Hey, I'm facing the same issue. I tried to recreate your plot but I only see it with the boundaries:

library(ggchicklet)
library(hrbrthemes)
library(ggplot2)

data("debates2019")

spkr_ordr <- aggregate(elapsed ~ speaker, data = debates2019, sum)
spkr_ordr <- spkr_ordr[order(spkr_ordr[["elapsed"]]),]

debates2019$speaker <- factor(debates2019$speaker, spkr_ordr$speaker)
debates2019$topic <- forcats::fct_lump(debates2019$topic, n=19)

db <- debates2019 %>% filter(debate_date <= as_date("2019-07-04")) # empty

ggplot(debates2019) +
  geom_chicklet(
    aes(speaker, elapsed, group = timestamp, fill = topic),
    colour = "#252a32"
  ) +
  scale_y_continuous(expand = c(0, 0.01), position = "right") +
  ggthemes::scale_fill_tableau("Tableau 20") +
  coord_flip() +
  labs(x = NULL, y = "Minutes Spoken", fill = NULL) +
  theme_ft_rc() +
  theme(panel.grid.major.y = element_blank()) +
  theme(legend.position = "bottom")

(On a side note: I was surprised to see that the debates data set apparently doesn't contain any debates from before September 2019 anymore)
