Summary of Changes

Hello @MinCrohn, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a bug where pausing the SelectionState incorrectly reset the interaction state, leading to undesirable side effects. It achieves this by refactoring the internal clearing mechanisms within SelectionState to provide more granular control over what gets reset. Additionally, it enhances the Wireframe class by incorporating a Type mixin, standardizing its identification, and includes a small refinement in how child elements are handled during specific merge operations.

Highlights

• SelectionState Logic Refinement: The internal clearing mechanisms within SelectionState have been refactored to separate the concerns of clearing the visual selection box from resetting the interaction state, providing more granular control.
• Prevent Unintended State Reset: The pause() method in SelectionState now exclusively clears the selection box, preventing an unintended reset of the overall interaction state to IDLE when pausing.
• Wireframe Class Enhancement: The Wireframe class now integrates a Type mixin, allowing it to be identified and configured using a type property instead of a generic label, improving consistency with other display objects.
• Children/Components Merge Strategy: A minor adjustment was made in the Childrenable and Componentsable mixins to conditionally re-add elements or components when a 'replace' merge strategy is specified, ensuring correct display list handling.

Code Review

This pull request addresses an issue where the interaction state was incorrectly reset when pausing the SelectionState. The fix involves refactoring the clearing logic to separate visual cleanup from state reset, which is a clean and effective approach. The pause method now correctly only clears the selection box, preserving the interaction state. Additionally, the PR includes a beneficial refactoring that standardizes the Wireframe component to use a type property for identification, aligning it with other components in the codebase. The changes are well-executed and improve both correctness and consistency.
