Looker Embed error [Deprecation] Custom state pseudo classes have been changed

[camilahp]

Adding a Looker Studio Embed report to my website generates several deprecation errors in the browser console:

[Deprecation] Custom state pseudo classes have been changed from ":--right-side-panel-single-column-width" to ":state(right-side-panel-single-column-width)". See more here: https://github.com/w3c/csswg-drafts/issues/4805

Is there any workaround to avoid all these errors? Probably Google should update the code embed.
