地图无法在 OnePlus 5T 上的 Chrome 上加载

Question

我正在使用Here JavaScript Web SDK，在BrowserStack上的每个设备和浏览器组合上一切正常。 但是，在运行 Chrome 77.0.3865.116 的物理 OnePlus 5T 设备上，地图无法在控制台中加载下面的堆栈跟踪。

我看到的是显示包括地图控件在内的地图容器，还简要显示了添加到地图中的两个标记。 然后，屏幕似乎重新绘制，标记消失，留下一个灰色的空地图，只有 UI 控件。

在运行 Firefox 的同一设备上，没有问题。 堆栈跟踪为：

我不确定报告此问题的最佳方式，因此在此处发布。 如果有人为我提供这样做的方法，很乐意提出一个适当的问题。

编辑 使用 MapBox 查看此错误消息后，一个原因是运行 WebGL 时打开的浏览器选项卡太多，但这种情况发生在只有一个选项卡打开的情况下

Answer 1

在改进 JS API 之后，问题"WebGL：CONTEXT_LOST_WEBGL：loseContext：context 丢失"不再可重现。
