Description:
When a relationship is set to "Draw Split" or "Hide", still beeing selectable and if user perform a selection through "mouse drag" over the "imaginary" path, the relation is selected.

This is a problem when there are many relations in "Draw Split" mode, and erroneously select them near other visible relationships.

Many times the user delete thats relations erroneously when select another visible relations.

How to repeat:
Add two tables and make a relation between them.
Set to Draw Split or Hide.
Make a selection with mouse in the space between the tables.

This results in a relation selection 

Suggested fix:
Do not make selectable the relations in both Draw Split and Hide modes.

Thank you for a problem report. I can repeat it with Draw Split (but not with Hide).

I check newly both modes and can repeat the bug.

When is set to "Hide", do not show  the relation selected, but if you perform a right click you can "delete" the relation.

That would require a relative big rework of the relationship handling, not worth for this rarely used feature. We will implement that differently later.
