Vertical threading view needs lines between replies

It's weird that you only see lines connecting replies if there's a fork in the convo. I suspect we need lines connecting consecutive replies too. Also, the root should be aligned with its replies, whereas currently they are indented, which confuses the model.

par example:

the linear replies just look a bit lost and broken without any lines connecting them here - almost like a rendering bug.
