What
Control requests now carry a yields-to-panels flag alongside whether the user invoked them, and roughly 25 descriptors hardcode it on, including goal proposals, embedded UI, the managed-settings security notice and sandbox network approval. Two consumers read it, and the active-dialog selector uses it to suppress a dialog while a panel is open. Nothing gates it; each descriptor sets the value as a constant.
Details
The flag travels with the request rather than being decided by the dialog code.
Absent entirely in v2.1.247, so the whole precedence rule is new this release.
