Audio only plays on one viewport (3D)

[olsongleb]

Tested versions

v4.2.2 stable.

System information

Windows 10

Issue description

I think I have found a problem similar to the one listed on the link, but only for the 3D camera. the sound (AudioStreamPlayer3D) is played only for the camera that was last specified as the current one. regardless of the fact that it is in another subviewport. #76634

Steps to reproduce

create a scene without a 3D camera, add Audio Stream Player 3D, two subviewports, each with a 3D camera. move the cameras in turn from the sound playback location. or in the attached project, you can move the cameras or change their current flag to hear it.
