Summary: Hiding a column (in a DataGrid) which contains a TimelineRuler as the headerview, doesn't hide the TimelineRuler when the column gets hidden. (This is the case for the patch in 160061)
<rdar://problem/27499300>
This doesn't affect any grids yet, but will become an issue once the Network waterfall column exists. The bug can still be reproduced, by making a small change to OverviewTimelineView: 1. Add the following to OverviewTimelineView's constructor: this._dataGrid.columnChooserEnabled = true; 2. Right click the grid header 3. Uncheck the "undefined" column => Graph column is hidden but ruler is still visible
