**Which product are you using?**  
PDF.js Express Plus

**PDF.js Express Version**  
8.7.0

**Detailed description of issue**  
When I create an annotation other than free-hand or rectangle, for example a circle, I get an error in the console.

```javascript
webviewer-core.min.js:709 Uncaught (in promise) ReferenceError: _super is not defined
    at Ea.Dh (webviewer-core.min.js:709:136)
    at gh.kga (webviewer-core.min.js:460:136)
    at ih (webviewer-core.min.js:13:46)
    at gh.lx (webviewer-core.min.js:11:167)
    at kh.next (webviewer-core.min.js:13:327)
    at ua (webviewer-core.min.js:14:43)

```

**Expected behaviour**  
It suppose to export my annotations in XML which I then save in my database

**Does your issue happen with every document, or just one?**  
Every document

**Link to document**  
{Provide a link to the document in question if possible}

**Code snippet**

```javascript
      // EVENT annotation changed ----------------------------------
      annotationManager.addEventListener(
        "annotationChanged",
        (_annotations, _action, { imported }) => {
          if (imported) {
            return;
          }
          this.showSavingAlert();
          async function save(saveAnnotations) {
            const XMLAnnotations = await annotationManager.exportAnnotations(); // Break at this line
            await saveAnnotations(XMLAnnotations);
          }
          save(this.saveAnnotations);
        },
      );

```
