| the same as https://crbug.com/576969#c3. |

| Additionally, this test also exercises a scenario where the new |
| FrameTree::generateLikelyUniqueSuffix can generate a suffix that |
| is not really unique (and where uniquness comes from numberOfTries |
| in FrameTree::ensureUniquenessOfUniqueName). |
