Component used: Paging 3.0.0
Version used: alpha02
Devices/Android versions reproduced on: Nokia 7.1/Android 10

Steps to reproduce:

• Clone the paging codelab on branch step11_loading_state: https://github.com/googlecodelabs/android-paging/tree/step11_loading_state
• Update to the paging version to alpha02
• Compile & launch sample app
• Make the data load that fetches the 2nd page of Github repos fail (e.g. throw an IOException, use airplane mode etc)
• Scroll all the way down to the "Retry" button
• Observe nothing appears to happen when tapping the retry button

Sample project illustrating the problem attached for convenience.

I've confirmed the retry call makes it all the way up to PageFetcherSnapshot and is collected from retryChannel. From there I got lost in the world of suspend functions and breakpoints without any useful context...

Further observations:

• Could not reproduce this issue with version alpha01.
• Retry works as expected when the initial data load fails (set FAIL to ON_INITIAL_LOAD in GithubPagingSource to confirm)
