🐛 AdMob inline banner is shown on iOS on top of the screen too (why?)

Bug report

Describe the bug I inserted a AdMob inline banner in a listview like described in the official codelab. The test-mode-banner is shown right in the listview on android and iOS. But on iOS-device the banner is shown too on the top of my screen and overlays my listview.

Steps to reproduce

This the code of my banner-widget:

import '../widgets/progress.dart';
import 'package:flutter/material.dart';
import '../google_mobile_ads/ad_helper.dart';
import 'package:google_mobile_ads/google_mobile_ads.dart';
import '../pages/home_page.dart';

class AdGrid03GoogleBanner extends StatefulWidget {
  int bannerWidth;
  int bannerHeight;

  AdGrid03GoogleBanner({this.bannerHeight, this.bannerWidth});

  @override
  _AdGrid03GoogleBannerState createState() => _AdGrid03GoogleBannerState();
}

class _AdGrid03GoogleBannerState extends State<AdGrid03GoogleBanner> {
  BannerAd _ad;
  bool _isAdLoaded = false;
  int bannerWidth;
  int bannerHeight;

  @override
  void initState() {
    super.initState();
    bannerWidth = widget.bannerWidth;
    bannerHeight = widget.bannerHeight;
    AdSize adSize = AdSize(width: bannerWidth, height: bannerHeight);

    _ad = BannerAd(
      adUnitId: AdHelper.bannerAdUnitId,
      //size: AdSize.banner,
      size: adSize,
      request: AdRequest(),
      listener: AdListener(
        onAdLoaded: (_) {
          setState(() {
            _isAdLoaded = true;
          });
        },
        onAdFailedToLoad: (_, error) {
          print('Ad load failed (code=${error.code} message=${error.message})');
        },
      ),
    );

    // TODO: Load an ad
    _ad.load();
  }

  @override
  void dispose() {
    // TODO: Dispose a BannerAd object
    _ad?.dispose();

    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      child: _isAdLoaded ? AdWidget(ad: _ad) : circularProgress(),
      width: _ad.size.width.toDouble(),
      height: double.parse((bannerHeight * 1.5).toString()),
      alignment: Alignment.center,
    );
  }
}

Expected behavior

I don’t expected that the banner is shown on the top of my screen too.

This also happens randomly with Native ads on both iOS and android in nestedscrollviews, singlescrollviews and listviews. The ad will briefly flash on top of the list and then correct itself. Sometimes it might even stay at the top until the user decides to scroll.

I have the same problem.
