>Safari has had a bug when opening a new tab and typing "search term" too quickly, it opens URL http://search%20term instead of doing a Google search. 8 years ago I've opened a bug for that which was closed as a duplicate, and just recently experienced this bug again.

While webkit might have some much needed improvements in the past few years, it is still the behind Blink and Gecko. Safari, the browser itself. Has been awful for the past 10 years. At least on Desktop. And some of these are not issue with Webkit because other webkit browser does it better.

The Address bar is far the worst compared to Chrome ( OmniBar ) and Firefox ( I believe it used to be call Awesomebar ). I have experience the same bug you mentioned and I believe I filed it way earlier.

Opening Bookmarks with too many items continue to pause and jank for 11 years now.

Tab Overview continue to re-render all the tabs. Causing Paging and Kernel_Task CPU spike. My Kernel_Task is currently 80TB at 240 days uptime. That is 333GB of write per day. Simply killing the SSD.

And no Tab Sleeping.

Apple just doesn't give a fuck any more about their software.
