Plot does not show hoverinfo for first data point when default hovermode or set to 'closest'

As written in the title, the hoverinfo for the first (bottom left) data point when layout.hovermode= 'closest' or kept as default does not appear.

# call library
library(plotly)

# reset fig
fig <- NULL

# add an extra line to check behavior on right hand side of graph
cars_one_extra_line <- rbind(cars,c(25,90))

# plot
fig <- plot_ly(cars_one_extra_line)
fig <- fig %>% add_trace(x = ~speed, 
                         y = ~dist, 
                         color = ~dist,
                         colors = 'RdBu',
                         type = 'scatter',
                         mode = 'markers')
fig <- fig %>% layout(hovermode = "closest") 
fig

This is shown in the screenshot below. If the cursor is moved to the point above, the hoverinfo appears.

In an effort to understand the behavior, I also tried other tags. Strangely, the hovermode = 'y' also seems to have a weird behavior. Things to note are the following:

• text is tilted,
• text is sometimes obscured beyond the viewing frame (not shown in this example but does occur in certain cases),
• text is sometimes shown twice but in two places,
• y axis position is not always shown (for points at the top and bottom of the chart)

Ejecute la reproducción de R proporcionada con plot_ly, marcadores de dispersión y hovermode establecido en "closest" o "y" para confirmar el comportamiento de hover ausente y mal formado. Rastree la ruta de renderizado de hover utilizada por el paquete de R y su salida de gráfico interactivo; se considera completado cuando el primer punto muestra hoverinfo y los casos de hovermode indicados se renderizan de forma coherente, sin recortes, duplicaciones ni posiciones de eje ausentes.
