[61.11.5] Docker page loads very slowly

In the current version, Docker page loads very slowly. I opened the debugging tool and observed that the requests were being blocked and remained in a "Pending" state. This issue greatly affects my use, as loading may take up to 50 seconds in the worst-case scenario.

I looked at this request and it returned HTML directly. The only reason I can think of is that the backend process is trying to retrieve the application icon. If that is the case, I think it needs to be improved, for example, by using WebSocket to handle the process.
