Pull Request Overview

This PR fixes a race condition in mobile end-to-end tests when opening Collabora documents. The test was flaky because it was trying to wait for multiple asynchronous operations simultaneously with the click action, causing timing issues.

• Separates the waiting operations from the click action to ensure proper sequencing
• Waits for load state, URL change, and response only after clicking the Create button
• Fixes the Promise.all pattern around editor.close() to prevent race conditions

Using Promise.all() with a single promise is unnecessary. Consider directly awaiting the waitForResponse call or removing the Promise.all wrapper for clarity.

Suggested change

	const respPromise = Promise.all([
	page.waitForResponse((res) => res.status() === 207 && res.request().method() === 'PROPFIND')
	])
	const respPromise = page.waitForResponse((res) => res.status() === 207 && res.request().method() === 'PROPFIND')
