Runtime.evaluate reuses the same JS execution context across calls in a
session. The previous expression used `const thumbs = ...` which throws
"Identifier 'thumbs' has already been declared" on the second loop
iteration, causing result.value to be undefined and JSON.parse to throw
"JSON Parse error: Unexpected identifier 'undefined'".
Fix by inlining the querySelector into a single expression with no
variable declaration, eliminating the re-declaration error.
