            Bug ID: 279110
           Summary: The ellipses do not appear when column-count and
                    line-clamp are used together.
           Product: WebKit
           Version: Safari 17
          Hardware: iPhone / iPad
                OS: iOS 17
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
          Assignee: webkit-unassigned at lists.webkit.org

On iOS 17.5 and later, when using column-count and line-clamp together, the ellipsis does not appear.
This occurs when switching the orientation of the device from portrait -> landscape or landscape -> portrait.
The CSS conditions that cause the issue are column-count of 2 or more and line-clamp of 1 or more to reproduce the issue.

This issue can sometimes appear differently when elements have complex inheritance.
(For example, the ellipses don't show up when you first enter the screen, but they do after you change the orientation of the screen...)

This issue did not occur in 16.7.5 when we checked it out.
There seems to be an issue with the layout configuration between the number of columns and line anchoring that is preventing the size from being recognized.

Could you please check this issue for me?
We've attached a link and screenshot to reproduce the issue.
