BlockPreview: Fix 'Infinity' is invalid 'minHeight' value warning

[Mamaduka]

What?

PR fixes Infinity is an invalid value for the minHeight CSS style property warning triggered when opening Query Loop setup modal.

Why?

tl;dr - Can't divide by zero.

The initial value of containerWidth is null before the resizer observer updates it. Because of this scale can be 0 and in JS Number / 0 = Infinity.

Test

const scale = null / 600;
const minHeight = 450 / 0;

console.log( scale, minHeight );

Testing Instructions

1. Open a Post or Page.
2. Insert a Query Loop Block.
3. Click on the "Choose" button to open the modal.
4. Confirm there's no warning in the console.
