Can this be replicated in core?

@boulaffasae, I attempted to reproduce the issue by utilizing a basic AJAX link to open a node page, and it functioned as anticipated. It appears that the problem may be specific to the "Webform" module and not related to the Claro theme. To assist in identifying and resolving this issue, it would be beneficial if you could recreate the issue without the contrib module and provide accompanying screenshots.

Please inform me if there is anything I may have overlooked during the replication process.

Thank you.

I had a look with @bnjmnm today at this and the z-index is present. So closing this as cannot reproduce.
