POS UI Extensions - Modal is not Full Screen as Expected

[xqwtsz]

Please list the package(s) involved in the issue, and include the version you are using

"@shopify/ui-extensions": "2024.10.x",
"@shopify/ui-extensions-react": "2024.10.x"

Also

api_version = "2024-10"

in the shopify.extension.toml

Describe the bug

The Modal component that is with the target:

export default reactExtension('pos.home.modal.render', () => {
  return <Modal />
})

is rendering as a modal, and is NOT full screen as expected.

Steps to reproduce the behavior:

1. Create a fresh POS UI Extension
2. Change the api_version in the shopify.extension.toml to 2024-07
3. Run npm run dev, everything is full screen, as expected.
4. Change the api_version in the shopify.extension.toml to 2024-10
5. Run npm run dev, modals look like modals and are not full screen.

Expected behavior

Expect the Modal to be full screen.

Screenshots

is just saw that this could be a feature and not a bug, depending on what you mean as Modal here

Because, what is being rendered is NOT a Modal, its a fully featured extension, and it is benefiting greatly from being a full screen extension.

If you think this should be a feature at least provide the option to be full screen or windowed as a prop.

This kind of visually breaking changes with no way to circumvent them, and no backwards compatibility, is not cool. If I want to use the 2024-10 version now, I can't, because everything shrinks to %50 of its size for the whole extension horizontally......
