fix(properties-panel): enhance element detection and error handling for nested structures

readme.hints.md

@@ -12,10 +12,16 @@ The properties panel had timing issues detecting rendered elements because:
 1. Added a 100ms initial delay to allow render completion
 2. Implemented recursive element search that:
    - Searches through nested children up to 5 levels deep
-   - Checks shadow roots of elements
-   - Handles complex DOM structures
+   - Checks both light DOM and shadow DOM for all elements
+   - Handles complex DOM structures generically
+   - Works with any wrapper elements, not specific to dees-demowrapper
 3. Added retry mechanism with up to 5 attempts (200ms between retries)
 4. Improved error messages to show retry count
+5. Comprehensive error handling:
+   - Errors in element search don't break the update cycle
+   - Individual property errors don't prevent other properties from rendering
+   - scheduleUpdate always completes even if createProperties fails
+   - Clears warnings and property content appropriately on errors
 
 ### Code Flow
 1. Dashboard renders element demo into viewport using `render(anonItem.demo(), viewport)`
