Power symbols display incorrect behavior with "Symbol x has been modified in library y" ERC rule.

Description

The issues is best described by the following steps to reproduce.

Steps to reproduce

1. Create a new schematic from scratch
2. Add a GND power symbol
3. Run ERC and notice no "Symbol x has been modified in library y" warning (ignore the "Pin not connected" error)
4. Open the symbol properties (right-click->Properties...)
5. Deselect "Show pin numbers" and "Show pin names" and press OK
6. Run ERC again and notice still no "Symbol x has been modified in library y" warning. This is expected, I'm only changing the visibility of graphic items not modifying the symbol itself.
7. Add a new GND power symbol using "Add power symbol" button
8. Run ERC again and now notice the "Symbol 'GND' has been modified in library 'power'" warning pointing to the new GND power symbol!
9. Update the new GND symbol from library and observer that the ERC warning does not go away.
10. Deselect "Show pin numbers" and "Show pin names" in the new symbol and notice still the warning does not go away
11. Delete the first power symbol, run ERC and notice still the same warning
12. Finally, update the remaining GND symbol from library and observer the ERC warning now goes away.

Note that this strange behavior only seems to effect power symbols, repeating the above with a normal symbol works fine.

With larger projects this makes for very confusing behavior which as you can expect can quickly lead to feelings of insanity.
