Logged errors are duplicated in the OUTPUT window

Issue

I've run through the "Build Image in Azure..." process a number of times and I've been tripped up by seeing errors logged multiple times. At first, I thought there was some kind of automatic retry happening.

I finally realized after seeing this a few times that the timestamps were identical and the output was just being duplicated.

Here are some examples:

Expected behavior

I expect to see each line of output exactly once in the OUTPUT window.

These logs are being streamed from Azure. Need to investigate whether the duplication is happening on service-side (in which case we can't do anything about it) or if it's happening on the client.

Related to #3616

This is the only extension where I have seen this kind of behavior. I've used App Service and Container Apps quite a bit and I've never seen the duplicate lines.

If it is on the server side, it would be great to open an issue against that team.

I'm going to resolve this as a dupe of #3616, it appears to ultimately be the same issue, just manifesting differently.
