Can confirm as well, although to my recollection it just shows up as if it's a word the transcription model heard, not "[foreign]" in brackets like with "[Music]" or "[Applause]". It's especially weird to me because I recall the auto-transcriptions being reasonably serviceable when they first rolled them out, only to degrade over time to the point where it was hallucinating the word "foreign" and dropping letters from words or using weird abbreviations (like "koby" for "kilobyte", "TBTE" for "terabyte", or, most memorably weirdly, transcribing the phrase "nanosecond-by-nanosecond" as "nond by nanc") if it didn't decide it heard another one entirely.

I also noticed a couple of months ago that YouTube seems to have quietly rolled out a new auto-transcription model that can make reasonable guesses at where capitalization, punctuation, and sentence boundaries should go. It seems to have degraded even more rapidly than the old one, falling victim to the same kinds of transcription errors. Although the new one has a different hallucination in silence and noise that it wasn't able to classify (which, incidentally, its ability to recognize things like music and applause seems worse than the old one's): where the old model would have hallucinated the word "foreign", the new one thinks it's hearing the word "heat", often repeated ("Heat. Heat.").
