Strange behaviour of the outlines

handles change relative positions when I grab a broken path. please check video attached.

I also noticed that using the arrow key combined with the option key, to move the selected point and/or nodes, doesn’t work on tangents as it did before.

When you move a point combined with option, the point doesn’t move allong the original angle.

The same thing happens to me in 2.3b 831.

This was bugging me for a while but never got around to fix it.
