trace shown in hoverinfo despite using hoverinfo='skip'

[ismirsehregal]

Coming from here.

After updating from R plotly 4.9.4.1 to 4.10.0 (and therefore updating underlying plotly.js library from v1.57.1 to v2.5.1 as mentioned in the NEWS) using hoverinfo='skip' along with hovermode = 'y unified' still shows a trace - only the trace name is hidden:

library(plotly)

fig <- plot_ly()
fig <- fig %>% add_trace(x = ~2:4, y = ~4:6, name = "yaxis data", mode = "lines+markers", type = "scatter")
fig <- fig %>% add_trace(x = ~4:6, y = ~4:6, name = "yaxis 2 data", mode = "lines+markers", type = "scatter")
fig <- fig %>% add_trace(x = ~6:8, y = ~4:6, name = "omit_hoverinfo", mode = "lines+markers", type = "scatter", hoverinfo='skip')

fig <- fig %>% layout(
  hovermode = 'y unified'
)

fig

Result using R plotly 4.9.4.1:

It seems this was already fixed in plotly.js:

plotly/plotly.js#5854

This does not occur using plotly.py 5.4.0 (with underlying plotly.js 2.6.3.)

import plotly.graph_objects as go

fig = go.Figure()

fig.add_trace(go.Scatter(x=[1, 2, 3], y=[1, 3, 2]))
fig.add_trace(go.Scatter(x=[2, 3, 4], y=[1, 3, 2], hoverinfo='skip'))
fig.update_layout(hovermode="y unified")

fig.show()
