Double click on note head produces weird results

Hello,

This is no serious problem but a bit confusing.

case 1

1) double click on the head of a note A
2) now click on a different note B

Only on the second click on note B it is highlighted

case 2

1) double click on the head of note A
2) double click on the head of note B

Clicking now on note B does not change anything, note A remains highlighted.

case 3

1) double click on the head of note A
2) double click on an articulation

Nothing happens. When you click on a different note the articulation appears.

I think double clicking a note should produce the same result as a simple click.

Thanks for any answers
