'identifier expected' error when using a string template followed by a pseudo-element selector

[Codex-]

Describe the bug (including copyable syntax)

When writing a styled component with a string template, if you use a template for the identifier (a) followed by a pseudo selector (:after) it results in an error .${a}:after {

Screenshot
Screenshots are alway useful!

To Reproduce

const test = ''
const StyledDiv = styled.div`
  .${test}:before { // <- identifier expected (ts-styled-plugin(9999))
    border-bottom: none;
    transition: none;
  }
`

Expected behavior
No error as this is a valid identifier
