I conducted testing on different themes to assess the issue's reproducibility. I can confirm that I was able to replicate the problem on some themes, while others remained unaffected.

Themes where I was able to reproduce the issue:

1. TwentyTwenty
2. Twenty Twenty-One
3. OceanWP
4. Kadence
5. GenerateWP

I found that the following themes did not exhibit the reported issue:

1. Twenty Twenty-Two
2. Twenty Twenty-Three
3. Astra
4. Blocksy
5. Spectra One

This discrepancy in behavior across various themes suggests that the issue may be theme-dependent

This needs to be reported on the ​Gutenberg repository.

To reproduce the growing preview on "Media and text in a full height container" now, you may need to start typing "media" into the block inserter search box.

When I tested with Twenty Twenty-Two, the aspect-ratio CSS on the .block-editor-block-preview__content element remained constant at 3.56083 / 1.

In Twenty Twenty, the aspect-ratio kept adjusting until it stopped at 0.583658 / 1, and a max-height of 245px was added late in that process.
