This is caused by mouse not always showing the + icon. The icon should be shown if you place the mouse between items.

Also, the new design has an icon always on the left side of the node:

Until we do it, dragging nodes with only widgets would be hard, so we could implement the new node deign ASAP.

Currently, adding a new element is fired on every up event, but I think we should fire it only when the down event was also in the list editor (or even in the right gap).

To be done after #6549 as the architecture of event handling may be revised there.

After fixes in #6540 I cannot reproduce adding new element (it's added only when cursor is plus, but this is expected). Also selecting with box and ending selection between elements didn't add elements to list editor.

The node is often not selected, but that's another issue: #6677

@sylwiabr please check it also and if you reproduce, please reopen this issue.
