CoreBoost v3.2.1

🐛 Fixed - Delay JavaScript Bugs

Favicon Not Displaying with Delay JS Enabled

• Fixed favicon not appearing in browser tab when Delay JavaScript feature is enabled
• Root cause: The delay loader script executed immediately on page load, keeping the browser main thread busy and causing browsers to deprioritize low-priority resources like favicons
• Solution: Added defer attribute to the delay loader script, allowing favicons to be discovered and queued during HTML parsing before the script executes

Delay JS Settings UI Issues

• Fixed "Use Default Exclusions" checkbox not staying checked after saving settings

  • Disabled checkboxes don't submit form data, causing the value to reset to false
  • Now preserves existing value when parent enable_delay_js is disabled
  • Defaults to true for new installations as intended

• Fixed inability to edit Delay JS options until saving

  • Added JavaScript to dynamically enable/disable Delay JS fields when the main checkbox is toggled
  • Users can now immediately configure options after enabling Delay JS without saving first
  • Custom delay field properly enables only when both Delay JS is on AND custom trigger is selected

Files Modified

• includes/public/class-delay-js-optimizer.php - Added defer attribute to delay loader script tag
• includes/admin/class-advanced-optimization-settings.php - Fixed sanitization to preserve checkbox defaults
• assets/admin.js - Added initDelayJsToggle() function for dynamic field state management
