There was a problem hiding this comment.
Hey there - I've reviewed your changes - here's some feedback:
- In the IntersectionObserver callback you call
WebVideoCtrl.I_HidPlugin()when the element is not visible, but there is no correspondingShow/Resumecall when it becomes visible again; consider adding symmetric behavior so the plugin is properly restored on route back/visibility change. - Before invoking
WebVideoCtrl.I_ResizeorWebVideoCtrl.I_HidPluginin the observer callback, add a defensive check thatWebVideoCtrlis defined and initialized to avoid potential runtime errors if the script has not loaded or the plugin is unavailable.

- In the IntersectionObserver callback you call `WebVideoCtrl.I_HidPlugin()` when the element is not visible, but there is no corresponding `Show/Resume` call when it becomes visible again; consider adding symmetric behavior so the plugin is properly restored on route back/visibility change.
- Before invoking `WebVideoCtrl.I_Resize` or `WebVideoCtrl.I_HidPlugin` in the observer callback, add a defensive check that `WebVideoCtrl` is defined and initialized to avoid potential runtime errors if the script has not loaded or the plugin is unavailable.Help me be more useful!
