### Problem Description

- `MvExpandOperator` is [leaving behind unclosed input blocks](https://github.com/elastic/elasticsearch/blob/4de2ffa2bcf9eba0b8d09fb5f13c217598d025ee/x-pack/plugin/esql/compute/src/test/java/org/elasticsearch/compute/operator/MvExpandOperatorTests.java#L137-L142). Should be closed by #100548
- `LimitOperator` is [leaving behind unclosed input blocks](https://github.com/elastic/elasticsearch/blob/4de2ffa2bcf9eba0b8d09fb5f13c217598d025ee/x-pack/plugin/esql/compute/src/test/java/org/elasticsearch/compute/operator/LimitOperatorTests.java#L100-L105). #100465
- `FilterOperator` is [leaving behind unclosed input blocks](https://github.com/elastic/elasticsearch/blob/4de2ffa2bcf9eba0b8d09fb5f13c217598d025ee/x-pack/plugin/esql/compute/src/test/java/org/elasticsearch/compute/operator/FilterOperatorTests.java#L128-L134). Should be closed by https://github.com/elastic/elasticsearch/pull/100465

### Steps to Reproduce

Remove the overridden `canLeak` implementation from `MvExpandOperatorTests`, `LimitOperatorTests` or `FilterOperatorTests` and run them.
