Describe the bug

My app contains a webview (using @nativescript-community/ui-webview), which was zoomable with pinch-zoom until my last update of @nativescript/android, which with needed because of another problem with new Pixel phones.
Many/most touch events do not seem to reach the website in the webview anymore, pinch-zoom has become impossible.

Expected behavior
Using 2 fingers to zoom works as it always did.

Sample project

I'm currently trying to do a small sample project on nativescript preview, but I can't get the webview to show there.
Will update the issue here once I get a working sample on nativescript preview or play.
Does anyone know of a sample I could fork/test with?

If anyone wants to take a look at my current attempt: https://stackblitz.com/edit/nativescript-stackblitz-templates-fblndg?file=app%2Fcomponents%2FHome.vue

Additional context

I know that not all modules list above are in their newest versions, for a patch release of our product I wanted to make as few changes as possible. Updating all of them to their newest version did not change anything.


Update: I redid the same project locally and it works as intended with ns debug android. Then trying ns preview also does not show the webview in the preview app.

To recreate locally: create a blank vue app and replace the with the webview tag pointing to a zoomable site of your choice.

Research direction

Start with the reproduction described in app/components/Home.vue: use a blank Vue app with the webview tag pointing to a zoomable site, then compare ns debug android with ns preview. Review the reported @nativescript/android update and webview configuration. Done means touch events reach the website and two-finger pinch zoom works again.
