Style attributes with numeric values are not rendered on server side

[fieteboerner]

Vue version

3.2.38

Link to minimal reproduction

https://stackblitz.com/edit/vitejs-vite-ats2me?file=generate.js&terminal=dev

Steps to reproduce

1. npm generate.js

What is expected?

<div><p style="-webkit-line-clamp:2;--myVar:1;">Foo</p><p style="-webkit-line-clamp:2;--myVar:1;">Bar</p></div>

To get the exact same style attributes in the DOM in the server side rendered version. So the UI is not broken or jumping by loading/hydrating a SSR-Page.

What is actually happening?

<div><p style="">Foo</p><p style="-webkit-line-clamp:2;--myVar:1;">Bar</p></div>

its about the empty style attribute in the first paragraph.

This issue only occures in the SSR process. By rendering the exact same component in the browser, the style attributes with numeric values are rendered fine.
