Scroll bar context menu option "Top" is not localized in Japanese

[eaodonnell-ni]

Description

We have a ScrollBar in our application. When you right click it, you get a context menu with the following options: Scroll Here, Top, Bottom, Page Up, Page Down, Scroll Up, Scroll Down

When our application runs in Chinese, all these options are correctly localized.
When our application runs in Japanese, instead of a localized version of "Top", that option is just "-". All of the other options are correctly localized.

Configuration

I see this in .NET 8
I can see this on a machine running Windows 10 Enterprise, AMD64.
However, someone else orginally reported this on a different machine that I don't know the specs of. The specs of the machine are unlikely to be related though.

Regression?

In June 2024, our application was using .NET Framework (I think 4.6.2). At that time, in Japanese, the Top option just said "Top" in English. So that was a different behavior, but still not a correctly localized string.
