On November 9, 2022, I filed FB11772168 with the sample project https://github.com/siracusa/NSTrackingArea-Bug.git which demonstrates a regression in the behavior of NSTrackingArea in macOS Ventura: mouseEntered/mouseExited callbacks are no longer triggered when the mouse enters/exits an NSTrackingArea during a drag operation, despite the .enabledDuringMouseDrag option being set on the NSTrackingArea.
On December 19, 2022, I made the mistake of adding a comment to FB11772168 item noting that I had since added some code to my app to work around this issue.
On March 2, 2023, Apple added a comment to my Feedback saying, "Thank you for letting us know that your issue has been resolved" and adding "this Feedback will no longer be monitored and incoming messages will not be reviewed."
@siracusa no good deed goes unpunished! 
@siracusa Never admit to support staff that there’s a workaround for their bug.
At best it will deprioritize the ticket severity; triaged as “broken with known workaround”. Worst case, “closed, won’t fix”.
@siracusa I think this is the same bug that’s blocking gtk3-based apps such as Inkscape from working on Ventura. https://gitlab.gnome.org/GNOME/gtk/-/issues/5305
@siracusa Wow. Not so long ago I dreamt and planned on transitioning into a career of developing iOS and Mac apps. After seeing how they treat people, nope. No way in hell do I want that job.
@siracusa haha you’ll never win this game.
