UML State Transition to self issue

Greetings,
First, I hope this the right group. I just started using the UML module and
see some useability problems with it.
In a state diagram, if a state transition leaves and enters the same state,
there are some resize issues.
If "Remove All Bends" is selected, the transition becomes invisible. It
looks like it changes to a single point in the middle of the state. The only
useful thing to do is delete it and re-enter it.
If the state is resized, the transition becomes invisible and appears hidden
inside the state graphic. Re-size back lets it reappear. Then, the
transition bends (vertices) can be moved outward so they will remain visible
when the state is again enlarged.
Judging by angles upon movement, it looks like the transition graphic is
referenced to the center point of the state object. If the transition
graphic was constrained so that its coordinates all stay at least on the
outside edge of any referencing state, that may be a solution to the issue.
I am excited about the tool and want to help improve it.
