Specification

No information provided

Summary

Currently Chromium applies the default action of a mouseup event (e.g. collapsing or committing a drag-selection in a text input) after the click event has already been dispatched. This violates developer expectations: a click handler that reads selection state sees stale data from before the mouseup default action ran. This change moves the mouseup default-action step to run before the click event is dispatched, so that selection (and any other mouseup side effects) is already settled when click handlers execute.
