研究方向
Investigate the CSS and template of the mat date picker component in the Angular Material source (likely in src/lib/datepicker/). Look at the container that wraps the calendar and identify CSS properties that cause horizontal overflow when resizing in touch UI mode. Check if there are any media queries or flexbox settings that should adjust. Examine related issues or PRs for similar scrollbar fixes. No linked PRs exist currently.
