Screenshots

Platform (please complete the following information):
OS: Windows 10
Browsers: Chrome
I can confirm on Windows 8.1 Chrome and Firefox, and Mac Chrome. No errors in the console.
Here's a fiddle: https://jsfiddle.net/xp3uq1e5/
The interesting part is that if you pull the window chrome up, at a point around the height of the popup it suddenly shows up.

I don't think it's CSS; the dialog stays up if you pull the chrome down. It looks like something in transition-show or another handler is pruning it if the window is taller than the dialog's height.
@FascistDonut
