Webpack 5 dealing with globals differently - Not found in changelog

[michael-whelan]

Bug report

version: Webpack 5.89

What is the current behavior?
When clicking on some elements of the site we redirect to partner sites (in a new tab).
The decision to redirect to a partner, to another area of the site or to block with a sign up request is made in a third party service.
As a result when the response is returned to allow the redirect we use globals.window.open(leadHref, "_blank") to open the new tab.
Since the upgrade to webpack5 we noticed that the globals.window.open(leadHref, "_blank") was being blocked on ios mobile with the note popup blocked.

If any changes have happened to the way webpack deals with the window.open in version 5 I could not find them noted in the changelog.

If the current behavior is a bug, please provide the steps to reproduce.
Visit site on ios mobile
Click store element on feed.
Witness that the new tab did not open.
Click a second time -> tab opens on partner site as expected.

What is the expected behavior?
Clicking on an element and after the decision to open a partner site we should open a tab with the partner site.
