  Log Message:
  -----------
  New test: TestWebKitAPI.TextManipulation.StartTextManipulationFindsContentInIframeInsertedLater is a flaky failure on iOS and Ventura
https://bugs.webkit.org/show_bug.cgi?id=254192

Reviewed by Wenson Hsieh.

The flakiness was caused by the race condition between when the 4th item is created after DOM mutation and when done is set to true.
Use srcdoc instead of setting innerHTML so that there is no DOM mutation, and therefore there will always be at most 3 items.
