Updates only the provided fields of an existing component library item (epic, work package, todo list, test suite). The description and internalNote fields accept HTML or Markdown and will be converted to the internal format. When the conditions array is provided, it completely replaces existing conditions. Conditions with id are updated, conditions without id are created, and conditions not in the array are deleted. Only library component items (component.projectId is null) can be updated through this endpoint.
