linebreaks are not rendered

[Madhusoodan Pataki]

Summary

I am trying to put newlines using the features of the katex (\ and \newline) but they are not working.
...

Expected behavior

\\ and \newline should render linebreaks
...

Actual behavior

it's not rendering the linebreaks
...

Steps to reproduce

Try this math expression
$$
(2i)^2 + (2j)^2 + (2k + 1)^2 \
= 4i^2 + 4j^2 + 4k^2 + 4k + 1 \
= 4(i^2 + j^2 + k^2 + k) +1 \
= 4(n) + 1\
= 2(2m) + 1\
= 2(p) + 1
$$

@mmpataki linebreaks work for me - see screenshot below.
I'm using version Windows 10, VS Code 1.52.1, Markdown+Math v2.5.1 from marketplace.

$$
(2i)^2 + (2j)^2 + (2k + 1)^2 \\
= 4i^2 + 4j^2 + 4k^2 + 4k + 1 \\
= 4(i^2 + j^2 + k^2 + k) +1 \\
= 4(n) + 1\\
= 2(2m) + 1\\
= 2(p) + 1\\
$$
