Material-components-android: [CollapsingToolbarLayout] RecyclerView bottom cut when coming back from another fragment

[NitroG42]

Description: Issue can be seen on the official Catalog app. This video will show the issue : https://streamable.com/y2r6l
To resume, you go to the bottom of a list - on a screen which contains a CollapsingToolbar.
Going to another fragment (by clicking on an item) and then coming back will make the list be "cut" on the bottom of the size of the collapsingtoolbar (minus the standard size of the toolbar it seems).
The only way to make the cut disappears is expanding the collapsingtoolbar (by going on top of the screen), then scroll back.
Again see the streamable link to see exactly the steps and the problem.
It is also reproducible on apps I worked on with a similar setup and behavior.

Expected behavior: Screenshots and/or description of expected behavior

Did you found a workaround for this problem?

Oh Google, this bug has been around for many years, and even in your project it is reproduced each time, is it really impossible to fix it?

Workaround is to add android:layout_marginBottom="?attr/actionBarSize" to your RecyclerView
