Some Adblockers such as uBlock Origin unfortunately block requests to https://api.leanplum.com/api . The JS SDK doesn't handle this very well however, as it seems to retry the request every ~400ms forever. In addition to spamming the console it also seems to significantly slow down the web app.

Expected Behavior

There are a number of possible solutions for this that can be applied, either one or many in tandem:

1. Implement exponential backoff for retries
2. Stop automatically retrying after a configurable time period
3. Stop retrying if the response object has status = 0

Actual Behavior

The SDK retries the request every ~400ms forever.

Steps to Reproduce the Problem

1. Install a browser Adblock extension such as uBlock Origin
2. Navigate to any website using the leanplum SDK
3. Trigger a leanplum API request via leanplum.forceContentUpdate() or similar
