Request to support window.open()

[ycmou]

Hello!

We would like to request PCM to support "window.open()" for decorating links with PCM attributes.

For context, because our website's click throughs needs to handle various other features like spam detection and event logging, we prevent the anchor tag's default behavior and instead ultimately delegate to use "window.open()" to navigate the user offsite. As such, we are not able to use anchor tag attributes to add decoration for PCM.

It would be great to have this support for us to fully integrate with PCM. For reference, Google's Attribution Reporting API offers it in this way: https://github.com/WICG/conversion-measurement-api/blob/main/event_attribution_reporting_clicks.md#registering-attribution-sources-for-windowopen-navigations, which does work for our use case.

One aspect to consider that was brought up by @johnwilander is to require "opt in to no opener so that the two windows cannot communicate after the second has been opened". See original thread in https://bugs.webkit.org/show_bug.cgi?id=231094.

Thanks!

Will this feature be supported in a future Safari update?

Hi! Thanks for filing. We avoid discussing individual browser plans here. But I’m tentatively in favor of this addition to the spec.
