Unable to interrupt kernel/query-cell after it has started creating cells

[ccjoel]

I can interrupt (abort) a query cell if the query cell is by itself, just "getting started". Pressing the interrupt square button on toolbar will stop execution and change it the aborted state and that's it.

However, leaving the query cell get started, once another cell is created or a workflow is running (able to reproduce outside workflows), there's no way to abort the cell with the interrupt button. The "kernel was interrupted" message will show on the server logs but nothing else will change- it'll keep going.

Recording of beta biome app. Able to reproduce on local beaker-kernel UI as well:

Is this expected?

As an aside, I didn't realize the agent had asked me if it should proceed with the workflow. That prompt is pretty useless- it'll start the investigation anyways. Once I realized it was waiting for an answer, answering "no" (dont proceed) was ignored.

In general I feel like our interrupt button only works inconsistently. When I updated to langraph #138 it seemed to work much better.
