    Memory Leak

    The ResizeObserver instance is stored in a global variable (tempObserver) but may not be properly cleaned up if the component is destroyed before the observer callback fires

    tempObserver= new ResizeObserver(() => {
    
      Section.scrollIntoView({ behavior: "smooth" });    
    
      tempObserver.disconnect();
      tempObserver = null;
    });
    tempObserver.observe( bodyElement);
    Performance

    Smooth scrolling is triggered on every results update which could cause jank and poor user experience if results update frequently

    Section.scrollIntoView({ behavior: "smooth" });

    Possible issue
    Prevent observer memory leaks

    The ResizeObserver should be cleaned up properly when component unmounts or when
    no longer needed. Add cleanup logic to disconnect observer and remove reference.

    docker/standalone.php [389-403]

     function observeResults() {
         const Section = document.getElementById("startStopBtn");
         if (!Section) return;
      
         let bodyElement = document.body;
    -    tempObserver= new ResizeObserver(() => {
    -     
    +    if (tempObserver) {
    +      tempObserver.disconnect();
    +      tempObserver = null;
    +    }
    +    tempObserver = new ResizeObserver(() => {
           Section.scrollIntoView({ behavior: "smooth" });    
    -      
           tempObserver.disconnect();
           tempObserver = null;
         });
    -    tempObserver.observe( bodyElement);
    - 
    +    tempObserver.observe(bodyElement);
       }

    Suggestion importance[1-10]: 8

    __

    Why: The suggestion addresses a potential memory leak by properly cleaning up existing observers before creating new ones, which is important for preventing performance issues and resource consumption.
