Research direction
The issue reports that when using linaria CSS in JS with a View component and setting catchMove={true}, the compiled output is bindtouchmove instead of catchtouchmove. The fix likely lies in Taro's compilation logic that transforms event props for mini programs. Investigate the babel plugin or transformer that processes JSX attributes, particularly in the WeChat mini program target. Relevant files may be found in packages like @tarojs/transformer or @tarojs/mini runner. Focus on the prop mapping for catchMove and determine where it is incorrectly mapped to bindtouchmove. Consider whether the issue is specific to using styled components or CSS in JS libraries that wrap components, potentially altering prop handling.
