Lucas Feliciano ca521b36e6 Manually call sheet.seal() to avoid memory leaks on with-styled-components example (#6107)
I was noticing some bad memory leak on my company's application and I ended up finding this github issue ( https://github.com/styled-components/styled-components/issues/1624 ) .

This comment ( https://github.com/styled-components/styled-components/issues/1624#issuecomment-425382979 ) caught my attention, which lead to this other issue on the repository of styled components website ( https://github.com/styled-components/styled-components-website/issues/329 )

After applying the changes on my project I noticed a huge improvement on memory consumption.

So would be nice to update the example or start a discussion on how to solve this properly

The idea behind the example

This example features how you use a different styling solution than styled-jsx that also supports universal styles. That means we can serve the required styles for the first render within the HTML and then load the rest in the client. In this case we are using styled-components.

For this purpose we are extending the <Document /> and injecting the server side rendered styles into the <head>, and also adding the babel-plugin-styled-components. (which is required for server side rendering)
