Why do you change align and justify properties here?

Specially align as the patch is only related to width (justify)?

[jfernandez, 2015/07/14 13:36:07]

This specific test case was designed to verify that stretching does
go beyond max-width, so now that we don't stretch auto-width
by default, we need to set it explicitly.
That's probably a mistake, since the new value does nothing since
height is set to a fixed value. I'll keep the old value.
