问题 I'm using Puppeteer for E2E test, and I am now trying to fill an input field with the code below: await page.type('#email', 'test@example.com'); It worked, but I found the email address was typed into the field one character by one character as if a real human being was typing.

问题 Since I've implemented server side rendering and managing the styles with styled-components , Im unable to edit styles in Chrome Dev Tools. The styles in devtools become italic and theres no checkbox to turn off/on specified style. It works properly in Mozilla. But why not in Chrome? Any ideas why does it happen? Thanks.
