Word Online on Lenovo Yoga Tablet Plus (Android 15): Lines Disappears

Description:

I am experiencing a device-specific issue in Microsoft Word Online using both Edge and Chrome browsers on my Lenovo Yoga Tabl Plus (Android 15, Snapdragon 8 Gen 3, 16GB RAM, 13 Inch Screen).

Issue details:

- When I press the Enter key, the current line disappears.
- Pressing the up or down arrow keys causes the cursor to jump two lines at a time, and the line at the cursor also disappears.
- This behavior is repeatable, disrupts editing, and results in loss of text.

What I have tried so far:
- Tested both Edge and Chrome browsers (latest versions, desktop mode); same result.
- Tried Gboard, Microsoft SwiftKey, and a physical keyboard; problem persists.
- Disabled Predictive Text, Text Magnification, Text Auto-correction, and all similar features.
- Cleared browser cache and cookies.
- Tried Incognito/Private mode in both browsers.
- Issue occurs in all documents in Word Online, not just specific files.
- Excel Online and PowerPoint Online do *not* have this problem on the same device.
- The issue does *not* occur when using Word Online on my Samsung S24 Ultra (Android 15) or Ubuntu laptop.
- The native Word app is unaffected, but lacks some needed features.
- I have the Microsoft Subscription and use it in my Desktop (Win 11). The tablet is for my travel.

This appears to be a rendering or input handling bug specific to Word Online with my device/browser combo. 

Any suggestions or is there any known workaround until this bug is addressed?

Thank you for your help!
