I held a water bucket and used it underwater on a swimming fish (salmon).

Actual result: I made the advancement “Tactical Fishing”, and the water bucket was empty afterwards, and I did not catch any fish.

Expected result: water bucket is emptied, and I do not make the advancement. Advancement can only be made by using empty bucket on fish or advancement can be made by using water bucket on fish, but results in advancement made and bucket of fish.

With an empty water bucket, I was able to catch a fish, resulting in a Bucket of Salmon (as expected).
