There are several mislabeled PRs missing:

[toast] Fix timer and limit edge cases #4933
Labels include docs, type: bug, component: toast. Changes ToastProvider, ToastRoot, ToastStore, and ToastViewport behavior around limits, timers, blur/focus, and touch swiping.
[toolbar] Fix disabled state and roving focus bugs #4968
Labels include docs, type: bug, accessibility. Changes Toolbar/Composite roving focus and disabled item metadata. This is user-facing a11y behavior.
[popups] Fix positioning and viewport edge cases #4925
Labels include docs, type: bug. Changes Dialog/Menu/Popover/PreviewCard/Tooltip popup state, viewport behavior, and useAnchorPositioning.
[form] Fix validation bugs #4894
Labels include docs, type: bug. Changes Form.tsx submit validation behavior for pending async validation.
[toggle] Fix grouped cancelation and JSDoc #4940
Labels include docs, type: bug, accessibility. Changes grouped Toggle cancellation semantics, not just docs.
[preview card] Keep inline preview anchored while open #4836
This is meaningful runtime behavior too, but it is not docs-labeled; it has type: bug and test.

There are several mislabeled PRs missing:

Yeah those ones were part of the sweep that touched docs as well. I think if it has the bug label it should be included even with docs as well?

Yeah those ones were part of the sweep that touched docs as well. I think if it has the bug label it should be included even with docs as well?

I think the idea was that they are mutually exclusive, you can have either new feature, bug fix, documentation fix, tests, etc. Obviously you can update the docs when fixing a bug or adding a feature, but the labels reflect the primary area.

Could you also include #5040? It doesn't seem entirely internal to me.
