Bug#1124534: Needed for dependency

[Jonathan Carter]

FWIW, I also require a newer version of textual, since the upstream 
replacement TUI for toot (called tooi) now depends on it:

It's not urgent, but perhaps another datapoint in knowing what to 
prioritise. textual is gaining in popularity so I can imagine that it 
becomes more critical over time.
