### Summary
After updating to v1.13.4 on Android, the Tab Switcher no longer displays note previews. Every tab shows a completely blank/black thumbnail instead of the note content.
### Steps to Reproduce
1. Update Obsidian to v1.13.4.
2. Open multiple notes.
3. Open the Tab Switcher.
### Expected Result
Each tab should display a preview of the note content, as it did before the update.
### Actual Result
All tab thumbnails are completely blank/black. No note content is visible.
### Environment
- Platform: Android
- Device: Samsung Galaxy A51
- Android version: 13 (One UI 5.1)
- App version: v1.13.4
- Reproducible: 100% (every tab, every time)
- Restarting the app and reopening the vault does not resolve the issue.
- This worked correctly before v1.13.4 (regression).
