Describe the bug
The connection point editor incorrectly moves/resets the location of some default connection points for some irregular shapes like the Trapezoid.

To Reproduce
Steps to reproduce the behavior:

1. Create a blank diagram.
2. Add a Trapezoid shape to the diagram and note the location of the default connection points (visible by hovering over the shape with the mouse cursor):
   
3. Right-click on the placed Trapezoid shape and click on "Edit Connection Points..."
4. Note that the placement/position of all connection points shown in the Edit Connection Points window is still correct:
   
5. Without changing any of the connection points, simply click "Apply" to close the dialog.
6. Note that the default connection points along the sloped edges of the shape have now been moved to the outer bounding box of the shape:
   

Expected behavior
I would expect that not changing any of the connection points in the window and clicking "Apply" would result in the connection points being in the locations shown in the "Edit Connection Points" window (i.e. the same locations they were in previously/by default).

draw.io version (In the Help->About menu of the draw.io editor):

• draw.io version 26.0.2

Desktop (please complete the following information):

• OS: Windows 10 22H2
• Browser: Microsoft Edge
• Browser Version: Version 131.0.2903.112 (Official build) (64-bit)

I tested the problem in incognito/private mode with all browser extensions switched off, write "yes" below:

• Yes

Additional context
Strangely, this does not seem to affect all non-rectangular shapes. I checked a limited set of irregularly-shaped (i.e. non-rectangular) default shapes.

These ones show the issue:

• Trapezoid
• Triangle
• Hexagon
• Step
• Diamond
• Parallelogram
• Circle

These shapes do not show the issue:

• Card
• Tape
• Cloud
• Cylinder
• Or
• And
