1) for (var i=0;i<130;i++)console.warn(i)
2) Resize the console so that it scrolls
3) at the bottom, expand one of the warnings to get the "(anonymous)"
4) Start a selection with the mouse inside the "(anonymous)" and drag upwards

Expected
Console viewport should scroll upwards smoothly, increasing the selection area.  Scrolling back down should preserve the start of the selection

Actual
Super janky scroll jumping occurs and the start of the selection changes
