Description

When building third-party block editors, you can set the height of the block canvas using the height prop in theory. (See https://wordpress.org/gutenberg-framework/docs/intro)

That said, this doesn't seem to work anymore

There are also other related issues:

• Now there's a border for the iframe of the block canvas
• The width of the block canvas is not 100%

Step-by-step reproduction instructions

Create a custom a block editor using the instructions in https://wordpress.org/gutenberg-framework/docs/intro and notice the height is not respected.

Alternatively, you can just use the "box" playground in the Storybook and change the "height" prop and see that it doesn't change anything.
