In Chrome versions 96 or newer the HTML renderer measures text slightly differently from other renderers. This bug requires a special case in cupertino/dialog_test.dart.

To reproduce

Make sure you have Chrome 96 or newer (this was reproducible in Chrome 96 in LUCI, and in Chrome 98 locally).

Sync to Flutter revision 8f58af8.

Run the test below in these modes:

• flutter test
• flutter test --platform=chrome --web-renderer=canvaskit
• flutter test --web-renderer=html:

Test:

  testWidgets('Off by 1px', (WidgetTester tester) async {
    final ui.ParagraphBuilder b = ui.ParagraphBuilder(ui.ParagraphStyle(
      textDirection: ui.TextDirection.ltr,
    ));
    b.pushStyle(ui.TextStyle(
      fontWeight: FontWeight.w600,
      letterSpacing: -0.5,
      fontSize: 51,
      height: 1.3,
    ));
    b.addText('The Title');
    b.pop();

    final ui.Paragraph p = b.build();
    p.layout(const ui.ParagraphConstraints(width: double.infinity));
    print('Height: ${p.height}');
  });

Expected behavior

In all cases the printed value of p.height should be exactly 66.

Actual behavior

The VM and CanvasKit modes print 66. However, the HTML renderer prints 66.296875.
