Publish scrollbar style/width CSS

[Sentiment]

By default, Publish uses a thin scrollbar:

But I prefer a standard scrollbar:

Until sometime this week (yesterday or day before, I believe), I was able to accomplish this with the following code in my publish.css:

body:not(.native-scrollbars) * {
    scrollbar-width: auto !important;
}

However, this stopped working, and the scrollbar reverted to the thin style.

Was there a recent update to the Publish back end? How should I modify my CSS to get back to the normal scrollbar?

Thank you!

Anyone have any tips? I have played with all (?) the scrollbar-related properties using the Chrome inspector, but nothing changes.
