Does `continued_fraction(d)` for a quadratic field element d compute whole preperiod and period eagerly?

New to sage, toying with continued fractions. I noticed that my code experiences performance degradation when I use continued_fraction(d), where d is represented as a QuadraticField element, and the C...
