/**
 * A horizontal scrollport's keyboard stop, and whether it takes a drag at all.
 * Android's HorizontalScrollView claims any sideways drag past touch slop even when
 * its content fits (the vertical ScrollView declines a drag it cannot scroll, the
 * horizontal one has no such check, and React Native's wrapper skips the claim only
 * while scrolling is disabled), so a fitting scroller would cancel a press that
 * drifts sideways and keep the page from scrolling for the rest of that gesture.
 * On Android it therefore scrolls only while its content overflows, unless TalkBack
 * explores the screen by touch: React Native's disabled horizontal scroller also
 * drops every hover event before its children see one, and touch exploration is
 * made of hover events, so a disabled scroller would hide its tabs, cells and cards
 * from a finger exploring them. An exploring finger drags without pressing anything,
 * so the scroller stays enabled then. Every other platform keeps a fitting scroller
 * enabled, as before: react-native-web's disabled scroller sets `touch-action: none`,
 * and a finger on it could no longer scroll the page.
