Assertions on HTML (webview) not working

Is there an existing issue for this?

[X] I have searched the existing issues and didn't find mine.

Steps to reproduce

The problem is related to maestro tests on Android. The Bitmovin player uses a Webview with HTML/Javascript to visualize the video player UI elements.

Clone the Bitmovin Samples Repo
Build and install the BasicPlaybackKotlin example app
- You need to provide a key in the AndroidManifest which can be retrieved via creating a free account on the Bitmovin page
Execute following config and flow via maestro
the assertion - assertVisible: "en" fails
- Asserting on a physical device works as expected
- Asserting on an emulator with google_apis_playstore works as expected
- Asserting on an emulator with google_apis does not work
- Asserting on maestro cloud fails. I assume, maestro cloud uses maestro start-device to create a device. It uses google_apis, see DeviceConfig

config.yaml

flows:
  - "DisplaysSubtitles.yaml"

DisplaysSubtitles.yaml

appId: com.bitmovin.player.samples.playback.basic
name: "Playback: Displays subtitles"
---
- launchApp
# toggle settings
- tapOn:
    text: "settings"
    retryTapIfNoChange: false
- extendedWaitUntil:
    visible: "subtitles"
    timeout: 10000
# open subtitle menu
- tapOn: "Select subtitle"
# select subtitle "en"
- tapOn: "en"
# !!! following assertion fails !!!
- assertVisible: "en"
# close settings menu
- tapOn:
    text: "settings"
    retryTapIfNoChange: false
# start playing
- tapOn:
    text: "Play/Pause"
    retryTapIfNoChange: false
# subtitle must be visible
- assertVisible: "Welcome to bitmovin's bitdash!"
- stopApp

Actual results

The assertion - assertVisible: "en" fails although visible. (inside a WebView) Using google_apis_playstore instead of google_apis would work

Expected results

Assertions behave the same on google_apis and google_apis_playstore (might be a general issue when parsing WebView hierarchy of google_apis vs google_apis_playstore)
