Sketcher: Some constraints can be selected with the mouse while others can't

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Problem description

In the sketcher I can select some constraints to delete them but others can't be selected. In the attached screen recording I can't select the two constraints on the right side. I assume it's because they are close together
