In "show-all" mode I want to display which page is currently displayed after scrolling to it, meaning I would expect the pageChange event to be emitted when scrolling to a new page.

Was this issue resolved? Don't see a page scroll into view event in the documentation.

Partial solution for 5.2.x: https://github.com/ColinT/ng2-pdf-viewer/tree/issue-223

Two-way binding causes an issue where the page jumps to the top when pageChange emits, since this is the default behavior for @input() page.

To prevent this, use the [page] and (pageChange) bindings separately.

I'll make a PR when this issue is resolved, but I'm not sure how to approach it at this point.
