Webpage card with embedded iframe, cannot click any links

I have an embedded webpage card in homeassistant using the following config:

type: panel
title: Dashboard
path: dashboard
cards:
  - type: iframe
    url: https://homepage.mydomain.com
    aspect_ratio: 50%
    allow: sandbox="allow-popups-to-escape-sandbox"

This behaves well for the homeassistant website and using homeassistant on android in chrome. Specifically, links set to href="..." target="_blank" correctly open in a new tab.

In the companion app however, clicking the links has no effect, and there is no feedback as to what is potentially the issue. Are there any known settings I am missing to allow this to work correctly?

teh app cannot handle pop-ups
