There's a usability issue in certain cases in browsers: when the
milestones table is at the bottom of the screen and it fills the screen
width completely, hovering over the link to delete a milestone makes the
"Delete milestone" tooltip cause a horizontal scrollbar. The scrollbar
makes it impossible for users to click the link.
We should probably fix this usuability issue; for now, I'm keeping the
test the way it was.
