taintedMessage not work on mobil

Description I have a problem with this superForm function option. It is set as true and works fine on Desktop, but in mobil devices (I have tried on Safari), is not working at all 😕

const form = superForm(data, {
		validators: zodClient(schema),
		taintedMessage: true
	});

Does any one know why this is happening?

My guess is the reason being

• the feature depends on the beforeunload event
• the event seems to be unsupported on safari mobile

Wow! That makes sense to me! I’ll try on chrome browser to see if it works!

Thank you! 😃

I guess I misread, it looks like very old versions did not have it , I hope it is supported according to this https://caniuse.com/mdn-api_window_beforeunload_event But anyways I would test it on a real device using safari, maybe there are other reasons why it might not fire that event Or the issue lies elsewhere..

I would try to

• clarify whether the form is tainted before navigating
• clarify if the event is fired at all
• if it is, find out why nothing happens visually (maybe blocked)
• render your own UI if you get the event
