• 当前 Bug 的表现（可附上截图）

takePhoto() 间隔10ms， 几次调用之后无法complete， complete回调函数不被调用。

• 预期表现

预期可以complete

• 复现路径

按照代码复现。

• 提供一个最简复现 Demo

captureTimer: function() {   const self = this;   setTimeout(() => {     if (self.nextCaptureFlag && Date.now() >= 10 * 1 + self.lasttime) {       self.nextCaptureFlag = false;       self.addLog('start');       self.takePhotoForDetection();       self.lasttime = Date.now();     }     self.captureTimer();   }, 10); }, takePhotoForDetection() {   const self = this;   self.addLog('before take photo');   let cameraCtx = wx.createCameraContext();   cameraCtx.takePhoto({     quality: 'low',     success: (res) => {       self.addLog('take photo');     },     complete: (ddd) => {       self.addLog(`complete`);       self.nextCaptureFlag = true;     },     fail: (err) => {       self.addLog(`err`);     },   }); },
