Bug 45399

Created attachment 66913 [details] Test case for -webkit-line-clamp and visibility hidden issue When an element with visibility: hidden and -webkit-line-clamp: [anything] is appended to the DOM, the line clamp is not respected, even after setting visibility: visible or removing the visibility setting altogether. Note that the problem really seems to be that -webkit-line-clamp is ignored when rendering an element with visibility: hidden, not when making it visible (although the problem continues to persist then). Test case attached. Brief example: <div id="root"> <div id="container"> <p id="clamped"> Blah blah blah </p> </div> </div> 1. Remove #container 2. Set visibility: hidden on #container 3. Append #container to #root 4. Remove visibility: hidden on #container This also works if the element you remove and set visibility on is #clamped instead of #container. Just wanted to illustrate that it could be any node up the tree.
