Thumbnails do not update for landscape documents

[manuelVo]

Description

The Typst Webapp will never update the thumbnail for documents where the page width is larger than the page height. Instead, the thumbnail is stuck in the state it had before the page flipped to a landscape document.

Steps to reproduce:

1. Create a new document
2. Insert content so that a thumbnail is generated
3. Flip the document to landscape mode: #set page(flipped:true)
4. Make further, obvious changes to the document

The changes done in 4 won't be reflected in the preview, no matter how significant the changes to the document are.

I would like to add that this is also the case for any document that has landscape aspect ratio using the parameters length and height.

In other words, this bug is not necessarily tied to page(flip: true), but the fact that the page is landscape in dimension.
