Comment (by Ankit K Gupta):

 **Tested Additional Use Cases Apart from the Above-Listed Test Reports**

 - Since the issue was related to a **Block-based theme**, verified the
 fixes with a **Non-Block-based theme** like Storefront to check
 regression. Everything worked as expected ✅
 - Verified behavior when the **parent theme is not installed (or
 deleted)** while the child theme is still present. A message correctly
 appeared:
   _"The active theme is broken. Reverting to the default theme."_  ✅
 - **Before the fix**: The WP-CLI command (`wp theme list`) did not show
 the child theme in the theme list.
   **After the fix**: Verified that the child theme is now correctly
 listed. (Screenshots attached) ✅
 - Tested via created **Block-based (Twenty Twenty-Five) Child theme and
 Non-Block-based (Storefront) child themes** to ensure compatibility.  ✅
 - **Backward Compatibility**: Reverted back to **WordPress 6.7.2** after
 using the fix-specific branch. No issues appeared. ✅
 - Attached child theme zip for TT5 and Storefront for further testing. ℹ
 - No related console error or PHP errors observed while testing above use
 cases.  ✅
 - Full Site Editing works when Child theme is installed and active ✅
