Here is an optimized version of your program.
**Reasoning for changes:**
- The check `isinstance(custom_component, Component)` followed by `type(custom_component) is not Component` causes the interpreter to potentially look up the type and MRO twice per call.
- By storing `type(custom_component)` in `klass` and using `issubclass(klass, Component)`, you avoid having Python walk the MRO twice for the same object, which is subtly more efficient especially in tight loops and heavy use scenarios.
- Using `issubclass()` on the object's type is semantically equivalent to `isinstance()`, except it also works for custom metaclass scenarios and is very slightly faster when type is already known.
**All program logic and comments are preserved, only the relevant portion is optimized.**
* ✨ (freeze.spec.ts): introduce new function addFlowToTestOnEmptyLangflow to enhance test coverage and improve test reliability
* ✨ (freeze.spec.ts): increase timeout value for waiting for "built successfully" text to appear to improve test reliability
* ✨ (freeze.spec.ts): refactor code to check if firstRunLangflow is greater than 0 before calling addFlowToTestOnEmptyLangflow
🔧 (generalBugs-shard-9.spec.ts): update tags in test case to include @workspace and @components
♻️ (generalBugs-shard-9.spec.ts): refactor code to remove unnecessary steps related to sidebar search and node handling
