Boolean multi word property (kebab case) binding doesn't work

[mgibas]

Vue version

3.5.8

Link to minimal reproduction

https://stackblitz.com/edit/vitejs-vite-4jp7yp?file=src%2Fcomponents%2FMyCustomElement.ce.vue

Steps to reproduce

Run stackblitz

What is expected?

Both properties have 'true' as a value and I would expect it will be binded as an attribute.

What is actually happening?

Multiword (with a dash) Boolean property is not binded to the component.
