Glass partially renders in bedrock

I have encountered what I assume to be a bug in bedrock Minecraft where glass blocks(stained or not) would only render the panes closest to the player. What I had expected to happen was that all panes would render, as without some it can create some strange 2-d shapes, as seen in the images below. enabling or disabling experimental features doesn't change the results

 

How to reproduce the bug:

1. Create a world in bedrock (haven't got java to test it there)
2. place some glass block
3. Observe

 

If this is actually a feature, sorry.
