Inconsistent Replay Dragging

[2008Choco]

Describe the bug
Dragging a replay from the table starts dragging even from unselected replays. For example, while having selected replays, dragging from the column headers or one of the replays that has not been selected will start the dragging process often negating functionality from the table.

To Reproduce

1. Select one or more replays
2. Click and drag the replays starting from either one of the column headers or an unselected replay

Expected behavior
If no replays are selected, the replay where the drag was initiated should be dragged. If one or more replays are already selected, the drag should not be initiated unless done from a selected replay.
