// @vitest-environment node
// Regression guard: xterm runs the custom key handler for keydown AND keypress.
// It discards a keypress carrying Ctrl/Alt but not one carrying only Shift, so
// a handler that returns false for keydown alone lets Shift+Enter's keypress
// through as a bare \r (submit). The Enter gate must therefore not be keyed on
// ev.type === 'keydown'; only the send-key fetch is.
