That's impressive. I'm glad they listened to you. Most of us are ignored for years if not forever.
Although Apple doesn't always respond when you file a bug report, they did fix an issue with Safari that I had reported. Within a few days, they emailed me and asked for more information. For the record, in a former version of Safari (Mojave), some sites that asked to fill a captcha would have the squares go blank after clicking just one. The next update to Safari fixed it.
