Summary: Exception thrown when hovering network waterfall graphs during reload. Steps to Reproduce: 1. Goto Network tab, reload inspected page 2. Hover over a record bar element in the grid 3. ⌘R to reload inspected page, while moving cursor in and out of the graph element => TypeError:​ null is not an object (evaluating 'this.dataGrid')​ (at ResourceTimelineDataGridNode.js:​377:​26)​ Note: The record bar's mouseleave event listener doesn't check that the node's grid reference is valid before using it. The node's grid reference is set to null when a node is removed from the grid, but before it's removed from the DOM. This occurs during page load as resources are reordered in the grid.
