Copied images rendering issue with Prisma theme

Bug: Export > Copy Image includes transparent space at the bottom

Description

When using Export > Copy Image, the output includes unexpected transparent padding at the bottom of the image. This may be related to using Untitled-1 as a workaround to render without a header.

Steps to Reproduce

1. Select an element
2. Go to Export > Copy Image
3. Paste the copied image

Expected Behavior

The copied image matches the visible bounds of the selected element.

Actual Behavior

The output includes transparent space at the bottom. See below - the text is placed directly underneath the image to illustrate the gap:

(Hard to see, so this text is directly underneath the image)

With a header it looks just fine:

I think adding an official [x] Header toggle would be the best solution and make it intuitive on how to remove the header.
