What seems to be happening is that if the test opens/closes the page real fast, the DOMContentLoaded listener init_all gets fired when some/all of the g*Pane global variables are not present (anymore?).

This results in messages such as:

[task 2019-03-13T22:57:27.819Z] 22:57:27 INFO - Console message: [JavaScript Error: "ReferenceError: gMainPane is not defined" {file: "chrome://browser/content/preferences/in-content/preferences.js" line: 76}]

in task bc13 in most debug builds, but for some reason this is not reported as an error in try build.

If you want to surface this error, switch init_all to be async and it'll start showing up in try.
