Undo may undo multiple operations at once

Phenomenon

When pressing Ctrl+Z to undo in Chrome, multiple operations may be undone at once instead of one operation at a time. This makes it difficult to undo to a specific point.

Reproduction example

1. Type several characters
2. Apply formatting
3. Type more characters
4. Press Ctrl+Z multiple times

Observed behavior

• Single Ctrl+Z may undo multiple operations
• Undo granularity is inconsistent
• Cannot undo to specific point easily
• Some operations are grouped together

Expected behavior

• Each Ctrl+Z should undo one operation
• Undo granularity should be consistent
• Users should be able to undo precisely
• Operations should be undoable individually

Browser Comparison

• Chrome/Edge: May undo multiple ops (this case)
• Firefox: Similar grouping behavior
• Safari: Undo granularity most inconsistent

Notes and possible direction for workarounds

• Implement custom undo/redo with fine granularity
• Save state after each operation
• Group operations explicitly if needed
• Provide control over undo granularity
