Bug with legend position and the title of the second y axis

When using plotly, I'm trying to have multiple axes on my graph, but when I switch the legend side to horizontal, the second y axis label overlays the ticks and is impossible to read. to show the problem, I'll use the exemple in the R plotly documentation, except that I add one line : legend = list(orientation = 'h'). The output it produces is attached. I can fix the problem by manually adding a marging, but I don't think that is the desired output of your function.

sorry for the broken reprex, I don't know how to add plotly as a library into the reprex.

ay <- list(
  tickfont = list(color = "red"),
  overlaying = "y",
  side = "right",
  title = "second y axis"
)
fig <- plot_ly()
#> Error in plot_ly(): impossible de trouver la fonction "plot_ly"
fig <- fig %>% add_lines(x = ~1:3, y = ~10*(1:3), name = "slope of 10")
#> Error in fig %>% add_lines(x = ~1:3, y = ~10 * (1:3), name = "slope of 10"): impossible de trouver la fonction "%>%"
fig <- fig %>% add_lines(x = ~2:4, y = ~1:3, name = "slope of 1", yaxis = "y2")
#> Error in fig %>% add_lines(x = ~2:4, y = ~1:3, name = "slope of 1", yaxis = "y2"): impossible de trouver la fonction "%>%"
fig <- fig %>% layout(
  title = "Double Y Axis", yaxis2 = ay,
  xaxis = list(title="x"),
  legend = list(orientation = 'h')
)
#> Error in fig %>% layout(title = "Double Y Axis", yaxis2 = ay, xaxis = list(title = "x"), : impossible de trouver la fonction "%>%"

Inizia riproducendo l’esempio della documentazione di R plotly con un secondo asse y e legend = list(orientation = 'h'); l’issue non indica alcun file sorgente né alcun test. Confronta il layout risultante con l’output allegato e considera l’issue completata quando il titolo del secondo asse y è leggibile senza aggiungere manualmente un margine.
