Glass treated as solid block is actually an intended fix. See recent Jeb's tweet: https://twitter.com/jeb_/status/1108312583596068864

This is already resolved.

Confirmed for 19w12b

Jeb mentioned in a tweet that glass is not going to suffocate anymore due to popular demand. See: https://twitter.com/jeb_/status/1108641007669821440

I tested this just now, and it seemed like the entity I pushed the glass block into just took damage because it was pushed by the glass block, but didn't continue to do so once it stayed in its head.

I can't reproduce this bug in 19w12b.

I can confirm @violine1101's observations. Mobs still do take damage when the piston extends, but not afterward. 

Here's a video showing the problem:

Can you please create a new ticket for that?
