styled-components: Line comments are not supported in multiline style declarations

[nora-heydecker-axa]

Describe the bug

A line comment after a multiline style declaration is not stripped properly.

This is the equivalent of styled-components/styled-components#5613:

const MyStyledComponent = styled.div`
  max-height: calc(
    ${someVariable1} + ${someVariable2} + ${someVariable3}
  ); // This comment causes a parsing error
`;

URL to minimal reproduction

I don't have a project, but I have added a failing test to the codebase that reproduces the behavior:

https://github.com/nora-heydecker-axa/plugins/pull/new/failing-test-issue-line-comment

Expected behavior

The line comment is stripped.

Additional context

styled-components rewrote its line comment stripper in styled-components/styled-components#5635, which broke our styles because we have closing braces after a line comment. it used to be that everything was ignored and kind of worked, but now styled-components strips our line comment, including the closing braces (because this plugin minifies them onto the same line), completely breaking the syntax.
we were able to work around it easily of course by just using a normal CSS comment or moving the line comment.
