Editing Post cache issue

[markwaters]

While trying to do this:

Edit a post

I encountered this error:

Shows previous version.

Steps to reproduce.

1. Create a post.
2. Publish Post.
3. Edit same post.
4. Edit page shows older version.
5. Hard reload browser with Control+Shift+R
6. Post reloads with latest correct contents.

I have cleared the Firefox cache , I have also tried disabling the PHP op-cache.
Seeing same issue in Chromium browser and Firefox on Android and Windows.

version = "0.9.9"
build = 2018020401

I have rolled back to dbdec00
with
git reset --hard dbdec00
and I am no longer seeing this issue.

Rolling forward this morning.
Not seeing this issue at commit 6e35161
But I am seeing it at 39d87d8

My bet is that this was introduced by the fixing of the cache header with ce203f7
