Make `event_data` warning suppressable?

Hi plotly devs,

The current implementation for event_data makes it such that the warning will display in nearly all instances where UI is rendered dynamically (such as in a shiny app). The warning is attached as a callback to the onFlush event which prevents it from being suppressed with suppressWarnings.

Can either:

• A vignette be provided for how to implement event_data with dynamically rendered UI in a modular shiny app without triggering the warning? -OR-
• An argument be provided to event_data to suppress the warning?

从 R/shiny.R 约第 151 行开始，跟踪在动态渲染 Shiny UI 时 event_data 如何将警告附加到 onFlush 事件上。比较所要求的两种结果：在 vignette 中记录模块化用法，或提供一个能够抑制警告的 event_data 选项；完成的标准是实现其中一种方案并验证其行为。
