Bug Description

Actual Behavior

Observed yesterday (3rd of April in master pipeline ).

our TS minbar is a safeguard to prevent shipping non supported TS features to our users.

for react(v8) test suite we specify dependencies like for react types via @types/react@17, which during test run will install latest 17 type version.

• version 17.0.55 worked as expected
• version 17.0.56 introduced breaking change making tsc throw error

Expected Behavior

minor/patch versions of 3rd party types should not introduce breaking changes - this needs to be fixed on DefinitelyTyped repo.
