Describe your changes

Added tests to verify that per-state callbacks in bidirectional components fire exclusively for their respective keys. The new test class BidiComponentStateCallbackTest ensures that:

  1. Only callback A is invoked when only state A changes
  2. Only callback B is invoked when only state B changes
  3. Both callbacks A and B are invoked when both states change simultaneously

GitHub Issue Link (if applicable)

Testing Plan

  • Unit Tests (Python): Added comprehensive test cases in BidiComponentStateCallbackTest that verify the correct behavior of state-specific callbacks in bidirectional components.
