Worked on the storybookjs/storybook repository to address a critical layout regression affecting CanvasWrap in Firefox ESR. Using React and TypeScript, reverted the use of min-width and min-height properties to explicit width and height, restoring the intended full-height layout and ensuring consistent cross-browser rendering. The solution was carefully linked to the original regression and previous pull request, with clear commit messaging and traceability. Validated the fix through regression testing across browser environments and documented the changes for future maintainability. This work focused on front end development, prioritizing layout stability and maintainable code in a collaborative open source environment.
