[BUG] Selftext preview is contracted after voting or saving it

[hmzuleta]

Describe the bug
When the selftext preview is expanded, voting or saving it will contract it, pushing the selftext post up and making it confusing for the end user. The user must then scroll up to continue reading the preview.

To Reproduce
Steps to reproduce the behavior:

1. Go to Settings/View customization.
2. Enable "Show selftext previews".
3. Go to r/redditsync and find a long selftext post.
4. Expand the selftext post.
5. Click the upvote button.

Expected behavior
The post vote should be updated and the selftext preview should be kept expanded.
