Application logs showing the errors + timestamps with two screenshots showing the respective UI elements

SUMMARY
Updating lots of widgets and themes in one go results in rate limits from pling.com. It seems like these requests don't have delays between them and are not retried after.


STEPS TO REPRODUCE
1. Have lots of widgets available to update
2. Go to the updates tab in Discover
3. Click on "Update All"

OBSERVED RESULT
Error messages about getting rate limited with a status code of 429 and an empty updates tab until refreshed.


EXPECTED RESULT
- Requests get send more slowly or the application waits a bit when receiving rate limits from a domain.
- Widgets or themes failing update keep being shown in the available updates list.
