PS v26.7 See the individual steps within an Action

I played with this a little more, and I now think the feature request is already taken care of in the current version, as shown in the demo below. What you see me do is:

1. Click the action’s gear icon to go into Edit Action mode. 
2. Scroll down to the step in the list where you want to start playing the action, and click that step to select it; it will now be highlighted. I selected the “Transform current layer” step. 
3. Click the Play button (the right-facing triangle) that you see at the top of the Steps list. The action starts playing from the step you selected, similarly to how it works in Classic mode. 

This action has a Duplicate Current Layer step, so normally the Star 1 layer would have been duplicated. But that didn't happen here, there are still just two layers: Star 1 and Background. The Duplicate Current Layer step was skipped, as well as all action steps before that one, because I chose to start playing the action from the “Transform current layer” step in the middle of the action.
