Opengl -a flag not working with opengl

[k4pran]

Description of bug / unexpected behavior

The behaviour of the -a flag is to output all scenes, however only a single scene is output when using the opengl renderer

Expected behavior

Expect all scenes to be previewed with the -p flag and output. I guess it is not applicable with interactive mode?

How to reproduce the issue

Run multple scenes with the -a flag and opengl renderer, for example python -m manim example_scenes.py --renderer opengl -a -pql

Code for reproducing the problem

class SquareToCircle(Scene):
    def construct(self):
        circle = Circle()
        circle.set_fill(PINK, opacity=0.5)

        square = Square() 
        square.rotate(PI / 4)

        self.play(Create(square))
        self.play(Transform(square, circle))
        self.play(FadeOut(square))

class CircleToSquare(Scene):
    def construct(self):
        circle = Circle() 
        circle.set_fill(PINK, opacity=0.5)

        square = Square()
        square.rotate(PI / 4) 

        self.play(Create(circle)) 
        self.play(Transform(circle, square)) 
        self.play(FadeOut(circle))
