🔧 Bug Fixes & Patches (6)

Test retries, when retrying on several failed tests, will no longer cause hanging during `cypress run`. Fixes #9040.
`multipart/form-data` is no longer wrongly encoded when using `cy.intercept()`. This should prevent `Unexpected end of multipart data` errors on the back end service where the request was pointing to. Fixes #9359.
`cy.contains()` no longer throws an error when a single quote is used inside its argument when RegExp. Fixes #8626.
Passing `capture: 'runner'` to a `cy.screenshot()` command inside `.within()` now screenshots the entire Test Runner as expected. Fixes #14253.
`Cypress.dom.isJquery()` now always returns a boolean instead of `undefined` sometimes. Fixes #14278.
`calledOnceWith` and `calledOnceWithExactly` sinon matchers no longer throw an error when used within Cypress. Fixes #9644.
