2.1.3 [CSS3UI:2018] Section 5.2 Overflow Ellipsis: the text-overflow property
V0008: The user cannot select or copy the ellipsed text
The specification states:
5.2. Overflow Ellipsis: the text-overflow property Name: 'text-overflow' Value: clip | ellipsis ... This property specifies rendering when inline content overflows its end line box edge in the inline progression direction of its block container element ("the block") that has overflow other than visible. ... ... § user interaction with ellipsis • When the user is interacting with content (e.g. editing, selecting, scrolling), the user agent may treat 'text-overflow: ellipsis' as 'text-overflow: clip'. • Selecting the ellipsis should select the ellipsed text. If all of the ellipsed text is selected, UAs should show selection of the ellipsis. Behavior of partially-selected ellipsed text is up to the UA.
The user cannot select or copy the ellipsed text.
