Hover incorrect when supplying color as argument in add_trace

I tried to create complex plot using add_trace. However there is problem with the hover when supplying color as argument: In this case the first and last element of the trace has no hover, sometimes it is only the first or only the last:

p1 <- plot_ly() |> 
  add_trace(
    type = "scatter",
    mode = "markers",
    x = 1:3,
    y = 1,
    color = 1:3,
    marker = list(colorscale = list(list(0, "red"), list(1, "orange")))
  )
p1

It works fine with

p2 <- plot_ly() |> 
  add_trace(
    type = "scatter",
    mode = "markers",
    x = 1:3,
    y = 1,
    marker = list(color = 1:3, colorscale = list(list(0, "red"), list(1, "orange")))
  )
p2

When doing the equivalent thing in python with

from plotly import graph_objects as go
fig2 = go.Figure()
fig2.add_trace(
    go.Scatter(x=[1,2,3], y=[1,1,1], type="scatter", mode="markers", marker={"color":[1,2,3], "colorscale":[[0,"red"],[1,"orange"]]})
)
fig1 = go.Figure()
fig1.add_trace(
    go.Scatter(x=[1,2,3], y=[1,1,1], type="scatter", mode="markers", color=[1,2,3], marker={"colorscale":[[0,"red"],[1,"orange"]]})
)

you get an error instead of an incorrect graph, which is better, I would claim.

Verwende die bereitgestellten R add_trace-Reproduktionen als Einstiegspunkt, vergleiche p1 mit p2 und überprüfe das gemeldete Hover-Verhalten an den Endpunkten. Erledigt ist die Aufgabe, wenn der Fall color-as-argument für den ersten oder letzten Punkt keine Hover-Informationen mehr verliert und die Beispiele als Regressionstest dienen.
