ignoredMessages not getting ignored

[wulffeld]

With this configuration the ignoredMessages are getting ignored and not sent to rollbar however if I leave out the checkIgnore option they will be sent to rollbar. That's not what the docs say I think or am I misunderstanding them?

Using latest rollbar.js. I've tested several times back and forth to verify this.

    var _rollbarConfig = {
      accessToken: "redacted",
      captureUncaught: true,
      captureUnhandledRejections: true,
      ignoredMessages: [
        /All ins elements in the DOM with class=adsbygoogle already have ads in them/i,
        /Uncaught TagError: adsbygoogle\.push\(\) error: All 'ins' elements in the DOM with class=adsbygoogle already have ads in them/i,
        /Uncaught TagError: adsbygoogle\.push\(\) error: No slot size for availableWidth=0/i
      ],
      checkIgnore: function(isUncaught, args, payload) {
        return this.ignoredMessages.some(function(ignoredMessage) {
          return ignoredMessage.test(args[0]);
        });
      },
      payload: {
        environment: "production"
      }
    };
