Summary by CodeRabbit

  • Bug Fixes
    • Fixed model listener property handling in prop merging: null or undefined model listener properties are now correctly omitted from the merged result instead of being preserved.

📝 Walkthrough

Walkthrough

The PR modifies mergeProps in the vnode utility to conditionally omit model listener properties (like onUpdate:modelValue) when both incoming and existing values are null, preventing these null entries from persisting in merged props. The test suite is updated with assertions to verify this new behavior.

Changes

Cohort / File(s) Summary
Model Listener Null Handling
packages/runtime-core/src/vnode.ts		 Updated mergeProps to skip assigning null model listener properties identified via isModelListener(key), preventing unwanted preservation of onUpdate:modelValue and similar model listeners.
Test Coverage
packages/runtime-core/__tests__/vnode.spec.ts		 Added assertions verifying that model listener properties set to undefined or null are not retained in merged props, contrasting with regular event handler behavior.

Poem

🐰 A model listener null, now wisely dismissed,
No longer preserved when both values have missed.
Event handlers stay true, but these special ones bend—
Clean props for clean models, our merger's best friend! ✨
