Want another fun Safari auto complete bug?

Have a tab open that is changing its title on an interval.

Try to type something in any tabs address bar and use the arrow or a mouse to try and pick a result, the focus will constant jump and reset to the beginning every time the title changes on any tab, making it nearly impossible to pick a result if its changing fast enough.

The auto complete list seems to be populated with web page titles in real time and the list is being modified causing the results to be rerendered.

I found this after trying to use a Super Micro IPMI that updates the title with the current FPS on every frame, had it in a background tab and couldn't get to a search result, oh the frustration and time that cost me to actually track down.

Reported it to Apple of course nothing.




This behavior sends me to undesired pages on a daily basis. Thank you for finally telling me what causes it!

It essentially makes basic keyboard shortcuts useless on safari.


Yup was able to replicate that with

   setInterval(() => document.title = `${Math.random()}`, 1000)


Holy sh!&*@#!t thank you. I had similar behaviour with a different remote BMC thing.


So that's how this happens. I always thought it had something to do with sticky arrow keys or something.


Reminds me of an issue on Windows I just figured out. My keyboard input kept getting yanked to the other PC.

For some reason, my mouse cursor moves back and forth when I use the arrow keys. Been happening for a while, but whatever.

Magic Mouse (KBM emulator) at some point got configured so that holding ctrl-shift-mousemove would snap the mouse to the PC in that direction.

Sooo, Ctrl-Shift-Left (highlight previous word, something I would do frequently [like just now to highlight and italicize 'frequently']) would end up also moving the mouse left a few pixels... which would send the mouse and keyboard over to the other PC.

Took me a few weeks to track that one down.


This has been annoying me for ages now and I couldn't always reliably replicate it. Nice find!


very similar experience trying to use Windows explorer while a group policy refresh is underway.
