Fixed a bug that caused invalid HTML.

## The Problem

On line 162, there was a bug:

```php
printf( '<div class="invp-map %1$s" id="%1$s-inner"></div>', esc_attr( $args['widget_id'] ) ) . wp_kses_post( $args['after_widget'] );
```

**Issue:** `printf()` echoes directly, so its return value (an integer length) was concatenated with `$args['after_widget']`, and that string was never echoed. This meant:
- The widget's closing HTML (`$args['after_widget']`, typically `</div>`) was never output
- This created unclosed/invalid HTML structure
- Could break page layout and cause JavaScript issues

## The Fix

I split it into two separate echo statements:
```php
printf( '<div class="invp-map %1$s" id="%1$s-inner"></div>', esc_attr( $args['widget_id'] ) );
echo wp_kses_post( $args['after_widget'] );
```

Now both the map div and the widget's closing HTML are properly output, ensuring valid HTML structure.

This likely explains the bug you were troubleshooting. The widget should now generate valid HTML.
