Linebreaks inside `${Component}:is()` selector breaks linting

[snelsi]

Describe the bug

The following code gives me console errors in VSCode, although the output selector and styles inside are working fine:

${Wrapper}:is(
    [data-theme="blue"]
) & {
    filter: invert(100%);
}

Where Wrapper is a styled component.

Screenshot

To Reproduce

Copy the code above and paste it inside any styled component declaration to reproduce.

Expected behavior

No syntax errors

Build environment:

• OS: MacOS 15
• VSCode Version: 1.61.0
• Extension Version 1.6.6

More info

The following code gives no errors, so it might somehow be related to linebreaks inside :is() and ${component} selectors:

// No component selector
div:is(
    [data-theme="blue"]
) & {
    filter: invert(100%);
}

// No linebreaks
${Wrapper}:is([data-theme="blue"]) & {
    filter: invert(100%);
}
