isBarOrChild is bugged

[adantart]

I don't understand (yet ;-) the "isBarOrChild" but it's the origin of a little bug.

When you select a line (a whole line) with the mouse from left to right, the menu appears. But when you do from the right (the end of line) to the left (beginning of the line), the menu is not showing.

It's because the isTargetOrChild and isBarOrChild are false, so the bar is not showing up.

I don't know how to fix it yet (well, forcing isBarorChild to true, but I guess this is not the solution ;-)
