Firstly, thanks for this plugin, it's immensely helpful!
However, when I'm editing JSX and am within a string template the autocomplete stops working. Seems it only looks for className= with single or double quotes. Would be helpful for React dev if it also worked within string templates.
I believe updating the RegEx on line 149 to something like \bclass(Name)?={*[`"\']([^"\']*)$ should do the trick.
These work:
className='fill-current border-'
className="fill-current border-"
But this does not:
className={`fill-current border-`}
