Autobreak creates new pages when there is already a new page

[mwoelk]

When using autobreak and using setPage() to add content to a previous page will lead to falsely added new pages and a continuation of the content at the newly added page (at the end of the document) instead of the already existing next page.

Reproduction:

• Create a new document
• Add two pages
• Set Page to 1
• Add content at the end of page that should break to next page

Observed behaviour:

• A third page is added and content continues here

Intended behaviour:

• No page should be added and content should continue on second page.
