Open iframe content external link correctly on android

Home Assistant Android version: Latest beta version of Home Assistant App.

Android version: 12

Phone model: Samsung Galaxy S10

Home Assistant version: 2022.11.1

Last working Home Assistant release (if known):

Description of problem: I use HomeAssistant with a card of type iframe to display my TV guide in a tab in a board. Here is the configuration of the card :

type: iframe
url: https://www.programme-television.org/?no_layout=
aspect_ratio: 50%

It works great to display the TV guide on the browser and the android app.

But if I clic on a link of the page, in the android app, nothing happens. In the browser, the link is displayed in a new tab.

What would be great for the android app, I see two options :

• open the content in the homeassistant app replacing the content of the iframe.
• open the content in the android default browser, as in the desktop version.

I would prefer the option one but there may be some technical elements in the good solution.

Traceback (if applicable, to get the logs you may refer to: https://companion.home-assistant.io/docs/troubleshooting/faqs/#android-crash-logs):

Screenshot of problem: Nothing to show. The problem is easy to reproduce.

Additional information: N/A.

Not mixed content related, I get a similar error when loading my server with https

Testing with the provided iframe URL shows the following console error for me:

Unsafe attempt to initiate navigation for frame with URL 'http://ha/iframe-test/0' from frame with URL 'https://www.programme-television.org/?no_layout='. The frame attempting navigation of the top-level window is sandboxed, but the flag of 'allow-top-navigation' or 'allow-top-navigation-by-user-activation' is not set.

Which, if I understand it correctly, is an intentional security feature, so I’m not sure why it behaves differently when using a browser. Maybe it is still allowed because it expects there to be a address bar/navigation UI in the browser but not when using a webview?
