Comment 12

[Ryan VanderMeulen [:RyanVM]]

Patrick, looks like you've cleaned up CPOW usage in this test previously. This particular failure is still one of the more frequent dead CPOW oranges we're hitting, though :(. Can you please take a look when you get a chance?

Comment 13

[Patrick Brosset <:pbro>]

Taking this one, the CPOW is quite obvious here. The test still uses getNode which access DOM node in the content page directly. I thought we had already eradicated them all, but some still remain.

Thanks for the review.
Here's a green try push: https://treeherder.mozilla.org/#/jobs?repo=try&revision=f695f7accecd&group_state=expanded
(eslint is red, but I've fixed the issue locally since then).
Going to land this.

Interestingly, both browser_styleinspector_csslogic-content-stylesheets.js and browser_inspector_initialization.js were disabled on debug e10s for docshell leaks. I wonder if that's still true after their deCPOWification.
