Bug in WordPress version: 6.7.1

[pateldeepak852]

Error display in head tag
code: <style>img:is([sizes="auto" i], [sizes^="auto," i]) { contain-intrinsic-size: 3000px 1500px }</style>

Need to add a dot in style tag attribute " .contain-intrinsic-size "

File Location: wp-include/media.php line no.: 2076

Thank you for the ticket. @pateldeepak852

For me, the current code seems correct, and there doesn’t to be an issue.

The :is() pseudo-class and contain-intrinsic-size property are used appropriately.

Adding a .contain-intrinsic-size class is unnecessary and redundant.

Please correct me if I'm misunderstanding something? OR please provide more details of the issue.

I think you're mistaking this for a CSS class name. contain-intrinsic-size is indeed a valid CSS property, see ​https://developer.mozilla.org/en-US/docs/Web/CSS/contain-intrinsic-size

The current CSS is indeed correct.
