The pull request has only one (non-merge) commit and in this case Github will use it as the default commit message when merging. The pull request title doesn't match the commit though ("fix(deps): update dependency eslint-plugin-storybook to ^0.11.0 - autoclosed" vs. "fix(deps): update dependency eslint-plugin-storybook to ^0.11.0"). Please update the pull request title accordingly to avoid surprises.
