If you have an edge, and add a label to it (either at the end or below, see the image) and then try to move things around, label position is changed unexpectedly. Any idea why and how to fix this behavior?

I mean, if you place the label "pin" on the line, it's okay, but as soon as it's just on the end of the line a bit beyond the line, the bug appears:

I would expect the label to behave the same, independently from the side of the end point it's located (to the lest of to the right). It looks like there is some trigger on positioning (relative/absolute) that fires incorrectly for this case
