In below codepen that uses plotly.js v2.23.1 is an editable shape attached to x2. When dragging and releasing the shape, it will jump to a new location, it will not stay where it was released.
You can check with newer plotly versions that the bug still exists. I chose the old version just to show that it is an old bug.
I had a brief look at the code and saw that for some reason the shape's xref is changed to 'paper'. This explains the jump, because the coordinates mean something different with xref 'paper'.
