Research direction

Start by reading src/uploader/uploader.wxml at line 13 and inspect how the uploader renders its object array with wx:key="*this". Check the surrounding markup and relevant WeChat Mini Program key behavior; done means establishing whether this usage is intentional or identifying a specific correction to make.
