Click and maintain and scroll toward the right side to select the numbers passed the ellipsis character Or 3. scroll with two fingers horizontally to move the text Expected: The string is scrolled so the selection makes visible the overflowed text Actual: The string is scrolling with the ellipsis but the rest of the text stays invisible. Notes: * This is working on Firefox Nightly 102 and Production Release 100. * Chrome Canary Version 104.0.5078.0 (Official Build) canary (arm64) exhibits the same behavior than Safari. https://bugs.chromium.org/p/chromium/issues/detail?id=13563 * Reported on https://github.com/webcompat/web-bugs/issues/104481 * Spec https://drafts.csswg.org/css-overflow/#ellipsis-scrolling This section applies to elements with text-overflow other than ''text-overflow:clip'' (non-clip text-overflow) and overflow:scroll. When an element with non-clip text-overflow has overflow of scroll in the inline progression dimension of the text, and the browser provides a mechanism for scrolling (e.g. a scrollbar on the element, or a touch interface to swipe-scroll, etc.), there are additional implementation details that provide a better user experience: When an element is scrolled (e.g. by the user, DOM manipulation), more of the element's content is shown. The value of text-overflow should not affect whether more of the element's content is shown or not. If a non-clip text-overflow is set, then as more content is scrolled into view, implementations should show whatever additional content fits, only truncating content which would otherwise be clipped (or is necessary to make room for the ellipsis/string), until the element is scrolled far enough to display the edge of the content at which point that content should be displayed rather than an ellipsis/string. and While the content is being scrolled, implementations may adjust their rendering of ellipses (e.g. align to the box edge rather than line edge).
