What TS compilation options are used for cypress.config.ts?

[alexeyr-ci]

I found cypress.config.ts can be used even when not included by any tsconfig.json in my project (I have one at the root and another in spec/cypress). So what options are used and can they be changed?

The reason I ask is because of a strange issue with importing cypress-cucumber-preprocessor, see https://stackoverflow.com/questions/76773181/how-to-correctly-import-a-module-with-module-exports-default for more details.
