The reason that those test_no_escapes_for_braces assertions pass is because they're only dealing with opening curly braces and in an f-string, they're treated as literal opening braces.

In the example you've given, the error occurs when the f-string handler encounters the closing curly brace without an opening one. It's the same as if you had written:

    >>> f'{{4*10}'
    SyntaxError: f-string: single '}' is not allowed

I will add a test to capture this specific case (backslash-escaped unicode opening bracken).
