Sourcemaps are broken in Cypress in TypeScript version 5

[jennifer-shehane]

Current behavior

Sourcemaps are broken in some version of TS 5. Something like the behavior below may happen where there is no sourcemap

Desired behavior

In order to get sourcemaps to work we have to do some monkeypatching to force the sourcemap options to generate them the way we expect. There's likely something that's changed in some version of TS 5 here.

This issue has not had any activity in 180 days. Cypress evolves quickly and the reported behavior should be tested on the latest version of Cypress to verify the behavior is still occurring. It will be closed in 14 days if no updates are provided.
