Flaky test: "memory eval and browse"

I've seen this test failing on PRs lately:

```
Unhandled exception:
Exception: Test 'memory eval and browse' failed: ══╡ EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK ╞═════════════════
The following assertion was thrown running a test:
The finder "Found 0 widgets with text "Any": []" (used in a call
to "tap()") could not find any matching widgets.

Inizia con eval_and_browse_test.dart e il test "memory eval and browse", quindi eseguilo nell’ambiente di test web di Flutter. Ispeziona l’azione che tocca il widget "Any" e confrontala con il fallimento CI collegato. Il lavoro è completato quando il test non fallisce più in modo intermittente durante l’esecuzione in CI.

Scritto dal modello di indicizzazione a partire dal testo della issue.
