I'm not sure how to test that. Unit-test? But it fixes the ICE in #62831. |

When 2 or more sequences share the same span, we can't use the precomputed map for their first set. So we compute it recursively. Fixes rust-lang#62831.

I added a test that gets an ICE before the fix and fails as expected (so the test passes) after the fix. |
