wxMac sometimes prints debug warnings (Adding duplicate * handler for...)

[davidfstr]

...that look like:

01:06:35 PM: Debug: Adding duplicate image handler for 'Windows bitmap file'
01:06:35 PM: Debug: Adding duplicate animation handler for '1' type
01:06:35 PM: Debug: Adding duplicate animation handler for '2' type

I don't remember exactly what sequence of actions causes these warnings to print. I think it happens when a certain type of dialog (like "Add Root URL" or "Add Group") is opened for the first(?) time. And I've only seen these warnings print on macOS.

Edit: Looks like the test_can_open_preferences_with_menuitem test on macOS triggers the warning.

Priority: Low

• These warnings don't seem to cause any problems by themselves. They won't be observed by most users. They are for a platform (macOS) that I expect to be infrequently used, relative to Windows and Linux.
