pymdownx.tabbed breaks relative-url-rewrite for nested imports #179
Description
I have the following example structure:
docs
├── a
│ ├── assets
│ │ └── screenshot.png
│ ├── page-a.md # imports _part-site.md
│ ├── _part-site.md # imports _screenshot.md
│ └── _screenshot.md # has image with relative path to assets/screenshots.png
├── b
│ └── page-b.md # imports ../a/part-site.md
└── index.md
While the on page-a the image is shown fine, on page-b it is not found, as the relative image url wasn't rewritten correctly.
This behaviour is only the case, when in _part-site.md the _screenshot.md is included into a pymdownx.tabbed tab.
Attached is a minimal example for this scenario
