Description of the Issue

When a selection is present, Ctrl+drag beginning within the selection should copy the selection. Instead, it replaces the selection.

Steps to Reproduce the Issue

1. Open a new tab and type: one two three four
2. Double-click two to highlight it.
3. Hold down the Ctrl key, position the mouse cursor over the w, press the left mouse button down, drag to the space between three and four, release the mouse button then release the Ctrl key.

Expected Behavior

As in 8.6 and prior versions (and most other editing windows), two should be copied to the space between three and four.

Actual Behavior

The original selection is deselected and the area over which the cursor was dragged is selected.

Workaround

It is still possible to drag copy by dragging without the Ctrl key (as if you were going to move the text) until the mouse cursor is at the position where you want to place the copy, then pressing the Ctrl key, then releasing the mouse button, then releasing the Ctrl key. However, this is an unexpected change in behavior which differs from the behavior of most edit controls; users may not recognize the need to adopt the new procedure and think it is no longer possible to drag copy at all.
