Reveal in Explorer Custom Shortcut Unresponsive

Hi Premiere Pro Team,

I have my keyboard shortcuts set to Alt+R to reveal a clip from the Timeline Panel to the Project Panel. I use the same Alt+R shortcut to reveal from the Project Panel in Explorer. However, this custom shortcut no longer works to reveal in Windows Explorer. It actually has not worked for a while now in various builds for the past year. I just never got around to reporting this bug. Here is a screenshot to illustrate the problem:

The keyboard shortcut revealing from the Timeline Panel to the Project Panel does work, just not from the Project Panel to Explorer.

I can still right+click on the clip from the Project Panel and select the option, which works. But that is extra clicking and takes me too long to find the option every time.
