Reiterating that it's kinda important to report issues directly to Apple, using their Feedback forms. I'm convinced they affect the development teams, but we should know our issues aren't the only issues. There is a priority. Sometimes its skewed to say the least, but staying silent is guaranteeing nothing will happen.
To give feedback on Safari use
Feedback form Safari.
I just sent this:
"Safari 17.3.1:
Prerequisite:
having duckduckgo as primary search engine in Settings.
Do:
search by entering terms in the address bar and press return-key.
Happens:
results are shown at duckduckgo.com, but scrolling doesn't work as all content is frozen in place.
Expected:
results being shown at duckduckgo.com and scrolling to work normally."
