This section details on the original issue you should resolve

<issue_title>Map metadata from issue templates to NewIssue.md</issue_title> <issue_description>

I have issue templates with metadata, e.g.:

---
name: Bug report
about: Report a bug, help us improve
title: A clear title describing the bug from a user's perspective
labels: bug, needs triage
assignees: username
---

[...some body...]

When I create a new issue using this template, the title is brought through, but the rest of the metadata is not included.

I.e. this is the generated NewIssue.md:

A brief title describing the bug from a user's perspective

Assignees: 
Labels: 
Milestone: 
Projects:

[...some body...]

Would be great to populate the metadata fields based on the issue template!</issue_description>
