confirm/alert issues with Safari?

[Thibaut Barrère]

Hello,

I just posted a reproduction of an issue I'm meeting here:

https://github.com/SteveSanderson/knockout/issues/592

Basically under Safari only, the binding seems to wait for confirm/
alert to be done to impact data, whereas on other browsers, it works
as expected.

Is it supposed to work at all?

thanks,
