Italic property for other groups is forcedly ignored in italic string

[sharpchen]

Problem

Italic boolean property for highlight group(like @punctuation.special, @punctuation.bracket) are ignored inside a italic string. They are forcedly styled as italic.

Steps to reproduce

• make sure install treesitter parser for javascript
• create a js file and paste code sample

testEmails.forEach(email => {                                                                                    
    console.log(`Is "${email}" a valid email? ${isValidEmail(email)}`);                                            
});

• switch to a colorscheme that have string non-italic
• :hi @string gui=italic
