webp&文件夹名字太长

我最近鼓捣相册图片压缩希望能省点空间出来，在测试各种图片压缩效果的时候发现似乎不支持webp

另文件夹名字太长了点不到右边那个关闭文件夹的x，得拖到显示完整了才会出来那个x，建议那个x始终右侧置顶 且支持选中后按delete健关闭

Start by reproducing the reported behavior with a WebP image and a folder whose name exceeds the visible width, then inspect the frontend areas handling image formats and folder controls. Done means WebP images work in the comparison flow, the close control remains accessible for long names, and Delete closes the selected folder.
