Align environment inentation with & characters.

[jfab20]

Let's say I have the following document: test.md:

---
title: Test title
---

# test section

- Test bullet. 
  Some text
  \begin{align*}
  x^2 + 1 |
  \end{align*}

My cursor is in |. In align environments you use a lot the & character, and when I type it the following occurs:

---
title: Test title
---

# test section

- Test bullet.
  Some text
  \begin{align*}
x^2 + 1 &= 0 
  \end{align*}	

The line gets auto-indented and it removes the spaces before the line. This is not desirable because I'm typing in a list and
I want everything aligned with the list. How can I fix this?
