IssueTracker

Hi,

I am trying to combine selection library with paging library. Loading items from paging library works ok, but when I try to select item with long click (or with long click and dragging to select more items), the app crash:

    java.lang.IllegalStateException: Range start point not set.
        at androidx.core.util.Preconditions.checkState(Preconditions.java:131)
        at androidx.recyclerview.selection.DefaultSelectionTracker.extendProvisionalRange(DefaultSelectionTracker.java:281)

        ...

When you pre-load some pages with scrolling the RecyclerView, it crash after selecting more items with dragging. See attached videos.

Sample code attached.

Library versions:
    RecyclerView: 1.0.0
    RecyclerView Selection:1.0.0
    Paging: 2.1.0
