+/// Global flag that disables long-press selection for Android and iOS, as a hack for Superlist, because
+/// Superlist has a custom long-press behavior per-component.
+///
+/// This is a hack and is expected to be replaced ASAP. Issue: https://github.com/superlistapp/super_editor/issues/1547
+///
+/// The underlying issue is that the document layout components have a gesture mode of "translucent", which
+/// lets both the document component and the overall document gesture interactor both respond to the touch
+/// event. As a result, if a user long-presses on a component to re-order it, that long-press also triggers
+/// the long-press text selection behavior within the standard document interactor.
