Shutdown dialogue: it is hard to tell what option is selected (selected in the sense of having the keyboard focus)

[LinuxOnTheDesktop]

As reported in this old Cinnamon bug report, it is - it remains, today - hard to tell which button is selected within the shutdown dialogue. This means that one has to squint a bit - or, on poor screens, a lot - to tell whether pressing will shutdown the PC, cancel the shutdown, or restart. Isn't that a clearly undesirable situation? Moreover, would it not be (though this is more of a genuine question) easy to fix? If it is: one more paper-cut bites the dust!

Here is the sort of visual contrast that would be welcome :

The issue is even more serious with Mint-X theme where it is impossible to tell which option is selected since all visual indications have been completely removed, and it affects all dialog windows.

Here's an example from Linux Mint's Text Editor (xed):

In the above image the "Close without Saving" option is selected. But I only know that because I pressed the left key twice before taking the screenshot. Keyboard navigation still works, it's only missing visual feedback in the theme.

IIRC this issue was introduced when the Mint-X theme was rewritten during the release of Linux Mint 21.
