Description

selectionCollapsed

Checks if a DOM selection is collapsed (has no range). Work around Chrome issue https://bugs.chromium.org/p/chromium/issues/detail?id=447523 (isCollapsed inappropriately returns true in shadow DOM) This function uses isEquivalentPosition to properly detect collapsed selections by comparing the focus and anchor positions, which works correctly in Shadow DOM. Example const selection = window.getSelection(); const isCollapsed = selectionCollapsed(selection);
