Hi.

It's reproducible each time I click the Connect button on

https://dongle.sonoff.tech/sonoff-dongle-flasher/

$ pkg_info -qI chromium
chromium-142.0.7444.175

$ sysctl -n kern.version
OpenBSD 7.8-current (GENERIC.MP) #125: Fri Nov 28 09:20:19 MST 2025
    deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

I actually don't have an expectation that this WebUSB flasher will
work, but I would not like it to kill the browser.
