Comment 6 for bug 1929596

After comparing this to a test server without this patch, I see that the alignment was off before the popover was ever added. So, considering that, and that the slight misalignment looks better than the copy number box being pushed to a second line, I squashed Gina's 3 commits into one and changed the "flex-row" back to "form-inline".
