| <meta name="assert" content="This test makes sure that, if the line with the ellipsis gets moved vertically because the height of previous lines grows, the ellipsis moves correspondingly; and that this happens even when the height of the line-clamp container does not change. This is the case even if the ellipsis completely displaces the line it's in."> |
