When Proton Mail for Android uses the dark theme with dark styling enabled for email content, emails from Google Play remain displayed with a light background. Google Play is a popular service, and these emails appear simple enough to convert to a dark style, as common dark-mode scripts and browser extensions can already handle them correctly.

Steps to reproduce

1. Enable the dark theme in Proton Mail for Android.
2. Enable dark styling for email content.
3. Open an email from Google Play.

Expected behavior
Google Play emails should also be converted to a dark style when dark styling for email content is enabled. This seems like a relatively small compatibility fix and would avoid having to switch email content back to the light theme because of this specific case.

Actual behavior
Google Play emails are broken while dark styling for email content is enabled.
