**Tell us about your request**
In the ECS service console, when running docker on Fargate, the logs have 2 different sorts applied. On each individual page, the logs are sorted newest to oldest. But across pages, the logs are sorted oldest to newest. This is inconsistent and confusing. Please pick a direction (ideally newest to oldest across the board!) and that should make it easier to read through the logs.

**Which service(s) is this request for?**
This could be Fargate, ECS

No repository files, tests, or code entry points are named. Start by reproducing log pagination in the ECS service console when running Docker on Fargate, then verify that ordering is consistent within each page and across pages, preferably newest to oldest.
