ariaBusy property
      
      String?
      get
      ariaBusy
      
    
    
The ariaBusy property of the Element interface reflects the value
of the
aria-busy
attribute, which indicates whether an element is being modified, as
assistive technologies may want to wait until the modifications are
complete before exposing them to the user.
Implementation
external String? get ariaBusy;
      
      set
      ariaBusy
      (String? value) 
      
    
    
    
Implementation
external set ariaBusy(String? value);
