IHostUiMountHandle.updateDocumentTitle() method

This API is provided as an alpha preview for developers and may change based on feedback that we receive. Do not use this API in a production environment.

Pushes the active application's page-title segment into the host UI.

Signature:

updateDocumentTitle?(pageTitle: string | undefined): void;

Parameters

Parameter	Type	Description
pageTitle	string | undefined

Returns:

void

Remarks

Called by the host whenever the active pluggable application sets a page title by emitting a document-title-changed event. The host UI composes the browser tab title as "{pageTitle} - {brand}". When called with undefined, the host UI falls back to the active application's manifest title.
