Qwen 3 235B (Thinking): Search Grounding Disabled?

For a few weeks now I’ve noticed that while using Qwen 3 235B (Thinking), Search Grounding is marked as unavailable. I find this odd, because I was using search with the model just fine a month ago.
Did something change on Alibaba’s end or was there some stealth change in t3?
Apologies if this doesn’t count as a bug per se.
