Describe the bug

When tapping or clicking directly on an existing word in the editor (HTML/CSS) to fix a typo or reposition the cursor, the text gets corrupted, duplicated, or merged unexpectedly (e.g., typing or editing creates overlapping words like ttext-align or colocolorbrckblack).

Steps to reproduce

1. Open any HTML or CSS file in Acode.
2. Type some code.
3. Tap/touch directly on an already typed word to move the cursor or correct a typo.
4. Try editing or typing new characters.
5. Observed: Text gets duplicated, corrupted, or attached together erroneously.

Expected behavior

The cursor should position cleanly on the tapped word/character without corrupting or duplicating the existing text.

Environment

• App Version: 1.13.1 (or 1.13.3)
• Source: F-Droid / GitHub
• Device: Android
• Keyboard: Gboard (or default keyboard)

Additional context

This seems to be an issue with touch selection/cursor positioning focus in the Ace Editor engine on Android touch devices.
