Plugin shorten_expanded does not work well with embedded attachments

Describe the problem you’re having:

When the plugin shorten_expanded is activated, attachments are displayed inline and the article is larger than the threshold of shorten_expanded the inlined images are below the expand button which makes the plugin rather pointless in this case.

The reason for this is that shorten_expand uses the height of the entire article but only moves what is in cdmContentInner into the contentSizeWrapper.

IMHO cdmIntermediate should be moved into the contentSizeWrapper as well.

tt-rss version (including git commit id):
commit id: 02bb26a9

Platform (i.e. Linux distro, PHP, PostgreSQL, etc) versions:
Archlinux
php 7.2.10
postgres 10.5

you’re right. i’ve tried it and it seems to work fine. luckily nothing depends on cdmIntermediate exact position in the DOM tree because it has to be reparented.

Works as expected now.

Thanks!
