Previously, the selection was accidentally "sticky" unless the player
went on to group a word with another. So if the user accidentally
clicked a word there was no way to unselect it without maging a bogus
grouping and then undoing that.
/* Second click on same word removes the word from the group. */
const idx = this.state.word_sets.findIndex(s => s.has(word));
const set = this.state.word_sets[idx];
- if (set.size === 1)

return;

const new_set = new Set([...set].filter(w => w !== word));
this.setState({
selected: null,
