The problem is a query of the general from (_, (_)) returns unexpected matches.
The problem is observed in version 0.20.8, but not in 0.20.7.
To reproduce:
npm install # sometimes takes a while
npx tree-sitter query queries.scm test.js
The output shows eight matches, among which the following two:
pattern: 0
capture: 1 - parent, start: (0, 0), end: (0, 10), text: `// test.js`
capture: 0 - child, start: (2, 4), end: (2, 15), text: `answer = 42`
pattern: 0
capture: 1 - parent, start: (2, 0), end: (2, 16), text: `let answer = 42;`
capture: 0 - child, start: (2, 4), end: (2, 15), text: `answer = 42`
The second one of these is correct, but the first one is not.
To try with other versions, change the tree-sitter-cli version in package.json.
