For a while, we have been setting child visibility to false, which
hid the horizontal line separators. However, I started scrolling in
the month view today and came to realize that they were disappearing
sporadically when scrolling upwards.
This happens because we use the `box-shadow` CSS property to apply the
box shadow a pixel above the month view row, which keeps it visible
in the view even when the month view row itself is no longer in
the page. Adding a pixel fixes that.
This reverts commit f4702dde1f.
