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:

plotly::event_data("plotly_relayout") オブザーバーと Firefox 開発者コンソールの websocket 出力から始め、描画操作をソケットメッセージおよび報告されたブラウザーエラーと比較します。矩形などの描画イベントが Shiny イベントのトリガーに失敗する理由を特定できる再現可能なケースが得られれば完了です。
