Image can not be displayed in some browsers on Android platform

Hi I stumbled upon a bug today. I think there is a bug in some browsers, such as qq/uc browser(google is normal) on Android platform (If the dicom file is not compressed or by jpeg-2000 compressed, it is normal and can be displayed in any browsers). And the bug doesn’t display in IOS platform. jpeg-ls.zip

My dicom file is compressed by jpeg lossless

I have debug cornerstoneWADOImageLoader step by step, then i can not enter this function (when taskType == ‘decodeTask’): ###cornerstoneWADOImageLoaderWebWorker.js

 if (taskHandlers[msg.data.taskType]) {
   taskHandlers[msg.data.taskType].handler(msg.data, function (result, transferList) {
     self.postMessage({
       taskType: msg.data.taskType,
       status: 'success',
       result: result,
       workerIndex: msg.data.workerIndex,
         }, transferList);
   });

Maybe there is an error inside the hander method (I can’t debug the internal method of the hander, so I am confused ).

If someone can use the browser test I mentioned on the Android platform, it should be easy to reproduce the problem.

This problem can only occur in some browsers (qq/uc etc.) on the Android platform.

I am confused, I don’t know how to solve this problem.

The attachment is compressed by jpeg-ls and can be used for testing.

Thanks.

@dannyrb Thank you for taking the time to test。 I found that JPEG-LS decode takes up more memory than JPEG LOSSLESS during the testing in browser，and some android devices browser can not display JPEG-LS image。

So I think this problem can be turned off and i will find some way to get the exception from web work code if i am free.

Thanks a lot.

@dannyrb I have created a repo for android devices test. This is test link
