Turtle visualizer warning that sequence values don't lie in domain accumulates

[gwhitney]

To reproduce, go to the Beatty DNA featured specimen. Click the Sequence Switcher, and select Formula. In the Formula input field, replace n with floor(sqrt(2)n) % 3. This will re-draw the Beatty DNA visualization fine, but multiple warnings that the sequence values do not lie in the domain will be left on-screen. Presumably they arise from well-formed partial versions of the formula that Turtle visualizer checked for consistency with the domain, and were not cleared once the formula got into a state in which it did harmonize with the domain.
