Originally filed @ https://github.com/webcompat/web-bugs/issues/51385

STR:

  1. go to https://steamcommunity.com/chat/
  2. log in

Expected: page loads
Actual: it doesn't

SyntaxError: invalid regexp group

The offending code is here:

t.prototype.ConvertBBCodeMessageContentToPlainTextMessageContent = function(e) {
    return e = (e = (e = (e = (e = e.replace(/\[emoticon\](.+?)\[\/emoticon\]/g, ":$1:"))
.replace(/\[url=(.*?)\]\1\[\/url\]/g, "$1"))
.replace(/\[url=(.*?)\](.*?)\[\/url\]/g, "$1 ($2)"))
.replace(/(?<!\\)\[\/?.+?\]/g, ""))
.replace(/\\\[/g, "[")
}

Note: this is broken in Safari as well.
