Performance > Timeline Events - Not clear when there is new data to load


When navigating the perfetto timeline events I noticed that new frame data won't show until we refresh the timeline.
This made navigating search results a bit confusing, as I was wondering why my new search results weren't showing up.

It might be worth exploring ways to communicate to the user that new data is available for them when they refresh.
For example something like the refresh button changing state when new data available,
and/or the search field having a little warning icon that that indicates new info is available

从 Perfetto 的时间线事件 UI 开始，复现 issue 中描述的搜索结果流程，包括在新的帧数据到达后刷新时间线。比较刷新按钮和搜索字段的可选指示方式；当用户能够清楚地知道何时有更新的数据可用，以及如何加载这些数据时，即视为完成。
