One partition affects another non-overlapping partition

[spring-raining]

Describe the bug
When there are two or more partitions and each partition overlaps horizontally or vertically, the wraparound process of one partition seems to affect the other partition.

To Reproduce

• Gist: https://gist.github.com/spring-raining/bd87a8be261682e0a33415578be4dcb7
• Test with Vivliostyle Viewer
  • Case 1: https://vivliostyle.org/viewer/#src=https://gist.githubusercontent.com/spring-raining/bd87a8be261682e0a33415578be4dcb7/raw/e994a2cc00141d027c01c74710e60301385e5163/case1.html
  • Case 2: https://vivliostyle.org/viewer/#src=https://gist.githubusercontent.com/spring-raining/bd87a8be261682e0a33415578be4dcb7/raw/e994a2cc00141d027c01c74710e60301385e5163/case2.html
  • Case 3: https://vivliostyle.org/viewer/#src=https://gist.githubusercontent.com/spring-raining/bd87a8be261682e0a33415578be4dcb7/raw/e994a2cc00141d027c01c74710e60301385e5163/case3.html
    • Case 3 seems to work well because each partition don't overlap horizontally and vertically.

Expected behavior
When one partition does not overlap, it must not affect the layout of the other partitions.

Vivliostyle.jsの過去バージョンをテストして、EAL実装の初期からの問題のようだということがわかりました。

2016.1 バージョンでテスト:
（テストはforkして旧バージョンがサポートしてない inset-* をtop/right/bottom/leftに変更したもの）
