Code indents don't appear in Markdown on Talk

[vrooje]

Expected behavior

If I write text within the code environment in Markdown on Talk,
    the indents should be
        preserved

Current behavior

When composing a Talk post, if I put in some code:

and then click the preview button, the code text is rendered with indents preserved.

However, once I click Submit and the post is created, the indents are not preserved,

but the indents are still there in the text of the post when I go to edit it.

It doesn't seem to matter whether the indents are spaces or a tab character.

Steps to replicate

Try putting in some indented text into a Talk post.

Test case here:
https://master.pfe-preview.zooniverse.org/talk/38/372?env=staging

Code blocks are wrapped in <pre>, which should preserve line-breaks and whitespace, but also styled to collapse whitespace:

white-space: pre-line

[eatyourgreens]

That style is set here:

Panoptes-Front-End/css/talk.styl

Lines 457 to 458 in 90f146e

	> pre
	white-space: pre-line

See #1602 and #1599.

Should be fixed by #7106.
