Description

Just one test took ~25 minutes due to shrinking. https://github.com/haskell/text/actions/runs/9201285542/job/25309228763?pr=590#step:6:1224

Should `noShrinking` be added?

Research direction

Start with the write_read test referenced by the linked GitHub Actions run and inspect how shrinking is configured. Reproduce the reported slow run, then determine whether disabling shrinking addresses it. Done means the test completes in a reasonable time without losing the intended coverage.
