3. Long tap on an article from the account.
4. Leave the article/page to load.
5. Tap on the tabs tray icon.

Expected behavior

• The content of the loaded sites is displayed for each individual site.

Actual behavior

• Blank tile is displayed for opened sites.

Device information

• Android device: Samsung Galaxy S9 (Android 8), Nokia 6 (Android 7.1.1)
