Custom source "unmounted" method not called

[mcjlnrtwcz]

Expected Behavior

unmounted method of my custom source should be called when I close file picker

Current Behavior

unmounted method of my custom source is not called

Steps to Reproduce (for bugs)

1. Create a simple custom source like

   const myNewCustomSource = {
   label: 'My new Custom Source',
   name: 'myCustomSource',
   icon: '<div />', // irrelevant for this example
   mounted: (element, actions) => {
       console.log("mounted")
   },
   unmounted: (element) => {
      console.log("unmounted")
   }
   }

2. Import and push your custom source to fromSources array in filestack's options
3. Open the file picker
4. Select your new custom source
5. Check console - your new source has been mounted
6. Close file picker
7. Check console - you won't see any info that it was unmounted

Context

I am trying to include custom source for filestack in a React app. I should be able to remove my components from the DOM when the user is done with picking the files from my custom source.
