after `e` fails on resume after exiting editor: "The cursor position could not be read within a normal duration"

[b-kaiser]

Pressing e to edit a task and quitting the editor crashes the TUI on resume 100% of the time on my system. Issue is independent of the editor (reproduces with both nvim 0.12.4 and vim 9,1 (tiny) and of the terminal (reproduces in GNOME Terminal, xterm, and alacritty). It first appears in v0.26.6 (v0.26.5 is fine). On 0.26.6 the TUI hangs and sometimes it leaks incrementing cursor-position replies to the screen or similar. On v0.27.0 the same failure is caught and shown as [taskwarrior-tui error]: The cursor position could not be read within a normal duration. v0.26.6 includes the crossterm 0.27→0.29 / ratatui 0.26→0.30 upgrade. Maybe crossterm#963?

Environment

• taskwarrior-tui: 0.27.0 (also fails v0.26.6); works on 0.26.5
• task: 3.4.2
• OS: Debian GNU/Linux 13 (trixie), kernel 6.12.94
• Terminal emulators (all reproduce): GNOME Terminal 3.56.2 / VTE 0.80.1, xterm(398), alacritty 0.15.1
• Shell: bash
• Editor: nvim 0.12.4 and /usr/bin/vim.tiny, both reproduce

Steps to reproduce

1. taskwarrior-tui
2. Select a task, press e
3. Edit (or make no change) and quit the editor
4. TUI breaks on resume — v0.27.0: error banner above. v0.26.6: hangs with incrementing cursor-position replies printed to the screen

Ruled out

• Minimal taskrc, no hooks (hooks dir empty)
• Local data path (data.location=~/.task, not mounted/network)
• Editor and terminal emulator (see above)
• Plain task <id> edit from the shell works fine
