Issue: Full-screen ColorFiltered creates an ultra-thin glitched line on top of the app
Labels: engine,platform-web,e: web_canvaskit,has reproducible steps,P2,found in release: 3.10,found in release: 3.11,team-web,triaged-web

### Is there an existing issue for this?

- [X] I have searched the [existing issues](https://github.com/flutter/flutter/issues)
- [X] I have read the [guide to filing a bug](https://flutter.dev/docs/resources/bug-reports)

### Steps to reproduce

1. Use Flutter 3.10.1
2. Use Flutter Web
3. Run app with a fullscreen ColorFiltered:

```dart
runApp(ColorFiltered(
  colorFilter: const ColorFilter.mode(
  Colors.transparent,
  BlendMode.srcATop,
), child: Container(color: Colors.black)));
```
4. Open page on a mobile phone
5. Enter fullscreen (can be done via `document.documentElement!.requestFullscreen()`)
6. Tilt your phone, so it has horizontal orientation

Not sure if fullscreen and horizontal mode is really neacesary, but at least for me the line is only visible if I do that (maybe because it's ultra-thin).

### Expected results

In the previous release of Flutter (3.7.0), the line didn't appear.

### Actual results

The line of one-pixel is display on the very top of the app.

Zoomed image of the line:
![obraz](https://github.com/flutter/flutter/assets/35242233/95aa064a-c5bd-468b-b487-5b1b82f70a9d)

The line appears to be a small fragment of Flutter's web loading animation (a blue progress bar), so it might be that the top line of pixels (that normally covers the loading animation) is just not drawn.

### Code sample

```dart
runApp(ColorFiltered(
  colorFilter: const ColorFilter.mode(
  Colors.transparent,
  BlendMode.srcATop,
), child: Container(color: Colors.black)));
```
