wxPreferencesEditor on OSX cannot be updated after first opened (Issue #22165)
Daniel Kulp
Describe the bug
On Windows (where wxPreferencesEditor is modal and destroyed each time), the pages get the TransferDataToWindow method called every time the user brings up the Preferences panel. Thus, the pages can be properly configured/updated to reflect whatever is the current state of the application.
On OSX, the TransferDataToWindow is ONLY called when the user first opens the preferences. If the user closes the preferences and then re-opens it, the pages do not get notifications to allow the pages to update.
In some applications, the preferences can be used to select a default view or default device or similar from some set of user created objects. The app needs to be able to update the list of objects whenever the wxPreferencesEditor is opened.
Expected vs observed behaviour
TransferDataToWindow is called whenever the preferences are opened (or page changed).

For the record, this comment explains what ought to be done here and why always calling TransferDataToWindow() is undesirable.
