Inconsistent double underlines across browsers #51506
Description
I'm seeing inconsistent "double underline" behavior on the web across browsers.
Steps to Reproduce
I have a brand new Flutter app with this code in main.dart:
import 'package:flutter/material.dart';
void main() => runApp(
MaterialApp(
home: Scaffold(
body: Center(
child: Text(
"Hello World",
style: TextStyle(
decoration: TextDecoration.underline,
decorationStyle: TextDecorationStyle.double,
),
),
),
),
),
);Chrome
80.0.3987.116 (Official Build) (64-bit)
Two underlines. No problems here.
FireFox
73.0.1 (64-bit)
One underline
Safari
13.0.4 (15608.4.9.1.3)
No underline at all.
