:data-index="index" is incorrect in DynamicScrollerItem demo

[lizyChy0329]

Clear and concise description of the problem

Suggested solution

key-field and index must be consistent otherwise the size of the computed could be 0.

// DynamicScroller
key-field="post_id"

// DynamicScrollerItem
:data-index="item.post_id"
:index="item.post_id"

my items were not being rendered and after doing what you posted, it worked, thx:

:data-index="index"
:index="index"
