[BUG] page.post template variable behaves differently when using `hexo serve` and `hexo generate`

[WeAthFoLD]

BUG Description

I'm using page.post variable when rendering pages to support multi-language.

When using hexo serve command, the variable works as expected and gives the page's absolute path.

However when using hexo generate command (or hexo deploy), when rendering blog posts, the page.post variable gives index.html, which is unexpected.

Bug Detail

I've create a repo to isolate and test this bug. I make the page.post variable display as header of the post, and it seems that when using hexo generate, the post.path and path stays the same between pages. When I create a test/hi.md static page, all other pages has path=test/hi.html.

Way to reproduce bug

See above.

I'm not sure if I'm clearly understand the issue. Is that possible to have some screenshots?

@NoahDragon Still using the Repo I created earlier, see this:

Note that the rendered page title (test/hi.html) doesn't correspond to the actual path(archives/2017/index.html). Here's how I used the code:

Let me have a look.

It's caused by fragment cache.
