Choice text + Gather + <Glue> + Next Paragraph sometimes makes next paragraph disappear (MacOS)

I noticed a weird behaviour when using glue. The paragraph (starting with glue) after a choice appears and disappears without clear reason. I really don't know how to describe it, so I made [this video](https://www.youtube.com/watch?v=Dd0uJylM2Ug).

When exporting for web, the browser renders the text as expected, without this problem.

The code used in the video:

```
I remember the first time Tim came to my practice. I was in the middle of a session with Ms S, when he arrived early, disturbing her mini lecture on the difference between an angel and a guardian.

* I can't say I didn't welcome the interruption.

- <> As with every time Ms S developed her theories on metaphysics, I tried to keep a straight face, occasionally letting out gentle "hms" and "ahas," hoping they showed more interest—a lie—than scepticism—my actual reaction. Actually, most of all, I hoped she got on with it, as soon as possible.
