chore: [deps] update components for base ui 1.9.0 - #1001
Combobox and Select accept readonly arrays for value and defaultValue in multiple mode, as Base UI 1.9.0 does. onValueChange still receives a mutable array, so handlers typed (value: string[]) => void keep working.
The Accordion and Collapsible docs say that a disabled trigger has the native disabled attribute and is left out of the Tab order.
The changelog has a Base UI 1.9.0 entry with the changes an app can see, including the disabled triggers and submenu changes from chore: [deps] upgrade base ui to 1.9.0 #993.
Base UI 1.9.0 accepts readonly arrays for multiple values. The wrappers now accept them for value and defaultValue too. onValueChange still receives a mutable array, so existing handlers keep their types.
Combobox and Select multiple-selection props, context values, and controlled-value state now accept readonly arrays. Their change callbacks remain typed to receive mutable arrays. Tests cover readonly values in both components. Accordion and Collapsible accessibility documentation now describes native disabled attributes and Tab-order behavior. The changelog adds a Base UI 1.9.0 entry with listed updates.
Merge Risk: Low · up to aa3be
The changes appear mergeable with documentation follow-up: the API table omits supported values, and custom disabled triggers can behave differently from the accessibility descriptions.

The combobox context keeps its mutable value type, since only the public props need to accept readonly arrays. The select test checks the checked state of the first option.

Select or remove an item with a readonly value, then assert that the callback receives a mutable new array and that the supplied value is unchanged. The current test checks rendering only, so it cannot detect a regression in this callback behavior.

Document readonly arrays of non-string values.
The new multiple-selection props accept readonly Value[], including arrays of objects, but the API table lists only readonly string[]. Document the generic value type for both props so users can discover the new support. (raw.githubusercontent.com)
As per coding guidelines, “Check each prop name and value against the component.”
