User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/118.0

Steps to reproduce:

1. Make sure browser.opaqueResponseBlocking == true.
2. Open the Network Monitor.
3. Load the attached file.

Actual results:

• The image is loaded successfully, but the Network Monitor doesn't show the information about the image request.
• The browser console says:

NS_ERROR_INVALID_CONTENT_ENCODING: Component returned failure code: 0x804b001b (NS_ERROR_INVALID_CONTENT_ENCODING) [nsIStreamListener.onDataAvailable]
    onInputStreamReady resource://devtools/shared/network-observer/NetworkResponseListener.sys.mjs:583

Expected results:

• Network Monitor should show the information.
