Comment 1

[Nicolas Chevobbe [:nchevobbe]]

probably need to enable nesting, I'll handle it

Comment 2

[BugBot [:suhaib / :marco]]

:emilio, since you are the author of the regressor, bug 1839638, could you take a look? Also, could you set the severity field?

For more information, please visit BugBot documentation.

Comment 3

[Nicolas Chevobbe [:nchevobbe]]

Attachment: Bug 1840076 - Set layout.css.nesting.enabled to true for layout/inspector/tests. r=emilio.

Since nesting is only enabled on Nightly at the moment,
a couple tests using nesting were failing on beta simulation.
