[Bug] News Feed - Force scrolling after the feed end its refresh

[bricefriha]

Description 📜

When we request a refresh and we scroll down the main feed a bit, once the refresh is done we are brutally brought back to the top.

To Reproduce ⚙

Steps to reproduce the behaviour:

1. Refresh the main feed
2. Scroll down a bit
3. wait until the refresh is done loading

Expected behaviour 🕵🏼‍♀️

The scroll position should stay the same. because let's say the user is in the middle of reading a headline, they shouldn't be brutally brought to the top.

Possible solution ℹ

If the scroll position is not at the top, add an annotation telling the user that some new articles are available.
