Footprint editor visual options erroneously brought into pcbnew

Description

When editing a footprint from PCBnew in the footprint editor (ctrl+E), changes to the visual style (e.g. "Show graphic items in outline mode") in the footprint editor will be applied to that footprint in PCBnew after saving.

The bug seems to be "contagious"; every footprint selected after leaving the footprint editor gets the visual style applied to it. Once, I managed to get the reverse to happen, where deselecting and reselecting the offending footprint caused the bug to go away, but I'm not sure exactly how I made that happen. The only reliable cure is to reopen the footprint editor, set the visual style back to normal, then save the footprint.

Steps to reproduce

Here are two copies of the same footprint:

Here, I've opened one for editing with ctrl+E, and clicked the "show graphic items in outline mode" button:

After saving and closing the footprint editor, now it has graphic items in outline mode on the PCB too!:

Now the other footprint has caught the bug as well, after clicking on it:
