🔧 Bug Fixes & Patches (6)

Fixed issue where the `onLoad` event was never being called when calling `cy.visit()` on the url Cypress is currently navigated to. Fixes #1311.
Fixed regression introduced in `3.1.4` that caused an `InvalidStateError` when visiting a page with an XHR request with a `responseType` other than `text` or `''`. Fixes #3008.
Fixed several issues in Chrome* versions >= 72 in the Cypress proxy that caused using `cy.visit()` with `localhost` to fail, or using `localhost` inside of the `baseUrl` configuration option. Fixes #1872 and #3252 and #1777.
Fixed another issue in Chrome* versions >= 72 where a scrollable command log would cause the entire application to be scrollable. Fixes #3253.
Fixed not correctly passing the `timeout` option for `cy.request()`. This should fix some instances where large `timeout` values would cause `ESOCKETTIMEDOUT` errors. Fixes #2669.
Fixed issue where Cypress would inject a script tag before the `<!DOCTYPE>` declaration when the document only contained the doctype declaration. Fixes #2617.
