This page (Cart Rules) designed in legacy theme.
I think the page must be migrated to new theme to solve this issue.
The grid tables that has action buttons in 3 dots style, has been designed by new theme.

Of course, you can work on the issue. We are happy to welcome new motivated contributor 🤗
Keep in mind that some of the page have been migrated, so the list might not be up-to-date. If you are willing to make a PR, I could double-check to update the list. Let me know :)
