in the ic-stepper.e2e.ts file there is a test that ensures the stepper width does not drop below 100px:

it("should keep the length of the step connect at 100px if a connectorWidth under 100px is given",

it would be good to add this as a cypress test

the e2e file can then be removed too

There's a ticket for the e2e Cypress migration, so this can be done within this ticket - https://github.com/mi6/ic-ui-kit/issues/2051
