Feature request: Espresso.openContextualActionModeOverflowMenu() should also work for DialogFragments

Description

Espresso.openContextualActionModeOverflowMenu() assumes that the "more options" ("...") menu button is part of the normal main Fragment. It does not work when that button is part of a DialogFragment that has been opened on top of the main Fragment.
This is most likely due to the fact that for onView() instructions (which are used within openContextualActionModeOverflowMenu() ) to work correctly for DialogFragments, they must be used in combination with ".inRoot(isDialog())". However, ".inRoot(isDialog())" is never called in openContextualActionModeOverflowMenu.
It would be desirable if openContextualActionModeOverflowMenu could also be used for DialogFragments in such a szenario.

Steps to Reproduce

• Start the test in a normal Fragment
• within the test, navigate to the DialogFragment that contains the "..." button
• call Espresso.openContextualActionModeOverflowMenu()

Expected Results

Espresso.openContextualActionModeOverflowMenu() should correctly open the menu.

Actual Results

"androidx.test.espresso.NoMatchingViewException" is thrown

Inizia individuando Espresso.openContextualActionModeOverflowMenu() e analizza come le sue istruzioni onView selezionano il pulsante del menu. Riproduci il problema con un DialogFragment e la NoMatchingViewException segnalata; il lavoro è completato quando il metodo apre il menu di overflow contestuale in questo scenario di dialogo.
