Before submitting a new pull request, please make sure:

• Test cases have been added/updated/passed for the code you will submit.
• Documentation has added or updated.
• Commit message is following the Convention Commit guideline with maximum 72 characters.
• Squash the repeat code commits, short patches are welcome.

Currently, the value of index obtained directly in webRender is always undefined, causing inserted elements to always be placed at the end of the parent container, which is incorrect in v-if scenarios(vue-next).
