play-services-oss-licenses:17.4.0 doesn't apply custom theme

[alecarnevale]

Describe the bug
Following the documentation on how to apply a custom theme for OssLicensesMenuActivity (v2) is not working.
Regardless of android:windowBackground set in the custom theme, OssLicensesMenuActivity will always render the default Material3 background color (soft pink, #FEF7FF).

To Reproduce
Steps to reproduce the behavior:

1. use play-services-oss-licenses:17.4.0
2. specify android:theme="@style/AppTheme" for android:name="com.google.android.gms.oss.licenses.v2.OssLicensesMenuActivity" in the manifest
3. setup your desired color for name="android:windowBackground" for your AppTheme style element
4. requested color is not used

Expected behavior
The background color of OssLicensesMenuActivity must be the value declared for the item android:windowBackground(as it was for version < 17.4.0).

Desktop (please complete the following information):

• Gradle version: 9.4.0
• Android Studio version: 2025.3.2
• Plugin name and version: play-services-oss-licenses:17.4.0, com.google.android.gms.oss-licenses-plugin:0.10.10

Hi, thanks for the report. I'm working on some related issues with 17.4.0, and will investigate this as well.
