Race condition

[crymall]

There is a race condition causing this code (in DFP.ts) to run even when the slot does end up having a contentUrl:

 if (!slot.getContentUrl()) {
            this.ad.isEmpty = true;

            dispatchEvent(
              Number(this.id.substring(this.id.length, this.id.length - 1)),
              LOG_LEVELS.WARN,
              'DFP Network',
              'Ad sizes missing. Bypassing ad.',
            );
            resolve();
}

This causes ad lifecycle events intended for after the ad renders to think that the ad is empty when it is not.
