Iframe embedding overflow widgets issue

[bitshadow]

Describe the bug

EmbedFrame is not resizing according to the widgets inside it. Widgets are overflowing out side of the main container.
Setting overflow: 'auto' from dev tools fixes the issue however we can't inject the styles in iframe.

To Reproduce

1. Create a dashboard with lots of widgets
2. Render the iframe with Light theme inside the parent app with black background.
3. You will see frame container is falling short of the combined widgets height.

Expected behavior

Background container should expand to the full widgets height.
