mobux 0.42.2

// Select mode in the live terminal view, under both renderers: a long-press
// on the touch overlay shows the rows on screen as real text on the
// renderer's cell grid, with the word under the finger selected through the
// browser's own selection and URLs as real anchors.
//
// Headless Chromium fires no contextmenu for an emulated touch long-press,
// so the specs dispatch the contextmenu Chrome Android fires for one.
//
// Run with: make test-native-select
