        output = gr.Video(label="Output Video1", height=250)

    with gr.Row():
        input_video = gr.Audio(label="Input Audio", sources=["upload", "microphone"])

Do you know why the overflow started happening in the first place?

[hannahblair]

I should've marked this as draft because this shouldn't be the fix really. Here's the space with the first implementation of it working fine and it didn't need this wrapper

Meant to ask this here:

Does the image already do this? Is this not something that Block in atoms can solve?

[hannahblair]

I've tried a few things to address it with Block but ultimately the issue is with the Upload button pushing out the source selection component in certain heights
