On EFL port, DownloadManager have the below issue:
In DownloadManager::convertHandleToDownload , The downloadID is inserted after Download::startWithHandle called.
But when download failed, the DownloadManager::downloadFinished  called by the below callstack, and check the downloadID for removing it, then ASSERT FAIL occured because the downloadID is not yet inserted.

WebKit::WebFrame::convertHandleToDownload          WebKit2/WebProcess/WebPage/WebFrame.cpp:243
 WebKit::DownloadManager::convertHandleToDownload  WebKit2/WebProcess/Downloads/DownloadManager.cpp:63
  WebKit::Download::startWithHandle                WebKit2/WebProcess/Downloads/soup/DownloadSoup.cpp:161
   WebKit::DownloadClient::didReceiveResponse      WebKit2/WebProcess/Downloads/soup/DownloadSoup.cpp:95
    WebKit::DownloadClient::downloadFailed         WebKit2/WebProcess/Downloads/soup/DownloadSoup.cpp:57
     WebKit::Download::didFail                     WebKit2/WebProcess/Downloads/Download.cpp:149
      WebKit::DownloadManager::downloadFinished    WebKit2/WebProcess/Downloads/DownloadManager.cpp:81


I think this situation is platform independent,
so I wonder why other ports don't have this assert issue when download failed.
Is there anyone give me a hint?

I think you need to make a test case for this crash.

I think [WK2] is proper bug prefix.

This is incorrect. If startWithHandle fails then the error should be called asynchronously.
