StickToBottomContext

Defined in: apps/website/.api-docs-entry/ui/build/ai-elements/conversation/stick-to-bottom-context.svelte.d.ts:24

Stick-to-bottom for streaming chat.

User latch:

• Any upward scroll / wheel-up → unlock (cancel pending pins)
• Reach the bottom again (or scrollToBottom) → latch

While latched: content ResizeObserver pins scrollTop at most once per frame. Pins use a synchronous flag (not a time window) so user scroll-up is never swallowed.

shouldPreserveBottomLatchAfterUpwardScroll()

function shouldPreserveBottomLatchAfterUpwardScroll(
   previous,
   current,
   options): boolean;

Defined in: apps/website/.api-docs-entry/ui/build/ai-elements/conversation/stick-to-bottom-context.svelte.d.ts:10

A shrinking transcript or a growing viewport can clamp scrollTop upward without user intent. Preserve the bottom latch for that layout movement; wheel, key, touch, and pointer input still win through directManipulation.

Parameters

Parameter	Type
previous	ScrollMetrics
current	ScrollMetrics
options	Readonly<{ directManipulation: boolean; stuck: boolean; }>

Returns

boolean
