Livechat widget broken in legacy browsers #12864
Description
Description:
When I enter a page with the livechat widget active in ie11, I get the following error:
SCRIPT1002: Syntax error
File: livechat.js, Line: 27, Column: 289
I went to that line and expanded it, it contains the following (I put a mark in the error placement):
!function() {
var e = Package.meteor.Meteor, o = Package.meteor.global, t = Package.meteor.meteorEnv,
s = Package.modules.meteorInstall, a = Package['babel-runtime'].meteorBabelHelpers, r = Package.promise.Promise,
n, c, l = s({
node_modules: {
meteor: {
webapp: {
'webapp_client.js': function(e, o, t) {
t.export({ WebApp: () => s }); <- The error happens here in the '()'
const s = { _isCssLoaded: () => 0 === document.styleSheets.length || Array.prototype.find.call(document.styleSheets, e => e.cssText && !e.cssRules ? !e.cssText.match(/meteor-css-not-found-error/) : !Array.prototype.find.call(e.cssRules, e => '.meteor-css-not-found-error' === e.selectorText)) };
},
},
},
},
}, { extensions: ['.js', '.json'] })('/node_modules/meteor/webapp/webapp_client.js');
Package._define('webapp', l, { WebApp: void 0 });
}();
Expected behavior:
It works in other browsers so it should work here also.
Actual behavior:
The widget is not rendered due to the error.
