Moving the toolbar a little too far left will create a new line if the other toolbar is on the same toolbar

When I drag the toolbar to the left (perhaps just to get it in the corner) using another toolbar in the same toolbar, the one I drag jumps to the “new” line, as if I were moving it down. This is pretty hard to explain, so here are a couple of diagrams.

Diagram A: I move the toolbar to the left and “accidentally” go too far to the left (well, only a couple of dozen pixels that users can easily make).

Chart B: This happens when the dragged toolbar falls down.

Remember that this is not a real problem, the location of the tools is the choice of the user, and you should not help in any way. You can count on the user ordering them logically.
