Espresso not triggering SelectionTracker

### Description

A ```longClick()``` with ```RecyclerViewActions.actionOnItemAtPosition``` does not trigger the selection of the item in a ```RecyclerView``` that has been passed to a ```SelectionTracker```.

### Steps to Reproduce

Set up a ```SelectionTracker``` with a ```RecyclerView``` in a ```Fragment```.

Use ```launchActivity``` and ```onActivity``` set the ```Fragment``` to the ```Activity```.

```longClick()``` an item in the ```RecyclerView```

Notice that nothing was selected.

It is worth noting that if debugging, and at a breakpoint, if you manually ```longClick()```, a selection will be triggered.

### Expected Results

The ```SelectionTracker``` to be triggered by a ```longClick()``` on an item in the ```RecyclerView``` passed to it, therefore triggering a selection.

### Actual Results

The ```SelectionTracker``` was not triggered by a ```longClick()``` on an item in the ```RecyclerView``` passed to it, and a selection was not triggered.

Reproduce the issue using launchActivity and onActivity with a Fragment, RecyclerViewActions.actionOnItemAtPosition, and longClick(), comparing Espresso 3.4.0 on Android 11 with a manual long-click. Trace why SelectionTracker is not triggered and verify that the automated long-click produces the expected selection.
