Function waitForUI5Stable

waitForUI5Stable(
page: WaitPage,
options?: WaitForUI5StableOptions,
): Promise<void>
Waits for SAP UI5 to report zero pending async operations.
Parameters
- page: WaitPage
  Playwright Page (or compatible subset).
- Optionaloptions: WaitForUI5StableOptions
  Wait configuration options.
Returns Promise<void>
Capability
ui5.waitForUI5

Remarks
Uses page.waitForFunction() to poll sap.ui.getCore().getUIPending() === 0. When skipStabilityWait is true, falls back to briefDOMSettle instead.

Timeout errors are wrapped in TimeoutError with code ERR_TIMEOUT_OPERATION.
Example
```
await waitForUI5Stable(page, { timeout: 10_000, polling: 200 });
```
