CssStyleSheet resolutionValue warning #992
Description
I'm seeing the following warning during execution
Jul 21, 2025 12:01:07 PM org.htmlunit.css.CssStyleSheet resolutionValue
WARNING: CSSValue '1x' has to be a 'dpi', 'dpcm', or 'dppx' value.
Looking at usages that could have caused this warning, I found https://developer.mozilla.org/en-US/docs/Web/CSS/image/image-set and checking existing source of org.htmlunit.css.CssStyleSheet#resolutionValue, it doesn't handle x as a valid suffix, which I think is an oversight.
