Description
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:

Research direction
Start by reproducing the supplied R example with hoverinfo='skip' and hovermode='y unified', comparing R plotly 4.9.4.1 and 4.10.0. Then inspect the underlying plotly.js hover handling; done when the skipped trace no longer appears in unified hover output while the other traces remain visible.
