Phone: a step's name stays on one line; every step says what it does

From looking at the real phone page after the fixes: a long command squeezed its step's name into
one character per line (執/行/指/令), and sending a file showed as 「工具」. The name keeps its width,
the detail is cut with an ellipsis, and send_file, react and view_demo_step have names; the window
says 「正在傳檔案給你」 instead of 「正在記下來」 while a file is sent.
