This might be related to the preprocessor.

I could be wrong, but it is possible that ~Processing 3.0+ uses the preprocessor to move size() from setup() into settings(). The mechanism may be slightly different then the simplified way it is explained in the public reference:

• https://processing.org/reference/settings_.html
• https://processing.org/reference/setup_.html
• https://processing.org/reference/size_.html

I have implemented a simple pre-processor here

I am not sure if it works in this situation. I will have a look soon.

Possibly related example of the Java preprocessor:
