I’ve seen this on my own device (author of the docs site here) but after a force quit and restart of safari was not able to reproduce.

Would you mind if I asked a few questions?

- does your device have remote debugging enabled on Safari?

- was your phone in low-power mode?

- did you first access the site through a WebKit in-app browser panel before opening it Safari?

- what version of iOS?

- what model of iPhone?

Those are my leading theories for what contributes to the flash happening. If you force quit and restart safari and / or reboot your phone does it work as expected?

Do you mean “Web Inspector”? Yes.

> - was your phone in low-power mode?

No.

> - did you first access the site through a WebKit in-app browser panel before opening it Safari?

No.

> - what version of iOS?

15.2

> - what model of iPhone?

13 Pro Max

I did force quit Safari and I no longer see the brief flash of target state when adding items to lists. But I didn’t check if I saw that immediately before doing force quit, sorry. I’ll write if I ever see that again.

I just tried it in a different browser, firefox focus (also ios) and got the blinking; it was slightly different, there seems to be some other issue there too. BUT after force quitting ff focus, the issue is again gone.
