Reproduction method

1. Have a book with multiple page
2. Go to the Overview page ("Versions" button >> "Overview")
3. The LiveData displays checkboxes. Click the down facing black arrow on the right of the top left checkbox and select "Select in all pages"
4. Select a status for the "New status" field
5. Click "Change status for all selected pages"

Expected result

All pages get their status changed.

Result

No page is processed for changing status.

Workaround

It's possible to make the livedata display more pages at once instead of 15, and then directly click the top left check box. This will select all the displayed pages, but actually won't behave the same and won't have the same issue.
