bug: swipe to go back is not passive, causing safari to throttle click events

Bug Report

Ionic version:

[x] 5.x

Current behavior:

Clicking multiple UI components in relativly short time results in click events being lost. “Fast” users have to double-click/tap almost every button/checkbox/ui element.

Since I am clicking too fast here, only every 2nd checkbox is marked as checked, even though you see that all of them were clicked.

Expected behavior:

Clicks events should not be lost.

Steps to reproduce:

E.g. create a ion-list with multiple checkboxes in it and check all of them without waiting too long between clicks.

Other information:

I guess this has nothing to do with the components (not specific to e.g. ion-checkbox), since it happens in the entire app (e.g. also in alert controllers with button clicks).

Seems to be only on iOS. Currently running on iOS 13.4, but that does not seem to matter. An old app of mine running on iOS 13.4 with ionic 4 does not have this issue (but it uses UIWebView instead of WKWebView, dont know if that does matter).

Thanks for the issue. This has been resolved via https://github.com/ionic-team/ionic/pull/21038, and a fix will be available in an upcoming release of Ionic Framework.

That version resolves the issue. Thanks!
