String 'leb' (silently) disables copilot

I lost an hour or more to this. 😭

But turns out that copilot disables itself (silently) if your code has the string 'leb' in it.

I was writing a small program to pull cards from scryfall in Dart. I wanted to pull the Limited Edition Beta cards, whose code is 'leb'. But I couldn't get copilot to work on the program (yet it worked on all my other projects). Eventually I tracked it down to the inclusion of the string 'leb'.

I worked around it by making the string 'l' 'eb' (dart will combine adjacent strings) and then copilot works fine. If you recombine the string, Copilot turns itself off it seems.

import 'dart:convert';

import 'package:http/http.dart' as http;

void main(List<String> args) async {
  final setCode = 'l' 'eb';
  final url = 'https://api.scryfall.com/sets/$setCode';

  final result = await http.get(Uri.parse(url));
  final map = jsonDecode(result.body);
  final searchUri = map['search_uri'];
  print(searchUri);
  final searchResult = await http.get(Uri.parse(searchUri));
  final searchMap = jsonDecode(searchResult.body);
  final data = searchMap['data'];
  for (final card in data) {
    print(card['name']);
  }
}

My only guess is that "leb" is a banned word? (I'm not cool enough to know what that word might mean.)

If it is some sort of banned word, some sort of message would help. Instead the Copilot logs just show 0 suggestions.
