Changelog Entry
Description
Fixed the Knowledge selector dropdown appearing behind the Create Folder modal, making it impossible to select knowledge items when creating/editing a folder. The issue was caused by missing z-index on the DropdownMenu.Content component in KnowledgeSelector.svelte, while the modal has z-9999.

Fixed
Fixed Knowledge selector dropdown (KnowledgeSelector.svelte) z-index issue where dropdown content appeared behind the Folder modal, preventing users from selecting knowledge items when creating or editing folders.
Security
None
Breaking Changes
None
Additional Information
Root Cause: The DropdownMenu.Content in KnowledgeSelector.svelte did not have a z-index specified. Since bits-ui's DropdownMenu uses a portal to render content outside the normal DOM hierarchy, and the Modal component uses z-9999, the dropdown was rendered behind the modal.
Solution: Added z-[10000] to the DropdownMenu.Content class to ensure the dropdown appears above the modal.
File changed: KnowledgeSelector.svelte
