plotly_relayout does not always fire

I will try and create a reprex if needed however I'm still trying to pin down an exact cause of this, for now I'll include relevant snippets.

In one of my projects I have been using the drawing capabilities of plotly.js:

    plotly::plot_ly(.......) %>%
      plotly::config(modeBarButtonsToAdd = list("drawclosedpath", "drawrect", "eraseshape")) %>%
      plotly::config(displayModeBar = TRUE)

I am listening to the plotly relayout event:

  observeEvent(plotly::event_data("plotly_relayout", session = session$rootScope()), {
    relayout <- plotly::event_data("plotly_relayout", session = session$rootScope())
    dplyr::glimpse(relayout)
    #.... rest of the code omitted
  })

The issue I am seeing is not all of the drawing events are triggering a shiny event. I have used the websocket viewer of Firefox developer console and the socket contains gaps where the relayout even should be. Hover events are being produced as the mouse is moved for the drawing of the shape however.

I'm seeing series of errors in the browser console:

Specifically for the rectangle draw:

Commencez par l’observateur plotly::event_data("plotly_relayout") et la sortie websocket de la console de développement de Firefox, en comparant les actions de dessin aux messages du socket et aux erreurs signalées par le navigateur. Le travail est terminé lorsqu’un cas reproductible identifie pourquoi les événements de dessin de rectangles ou autres ne déclenchent pas l’événement Shiny.
