Product designer and HTML/CSS person here, and in my experience it is the opposite. Designers and front-end focused people wh get a chance to work with Vue love it because it actually respects basic HTML/CSS/JS and doesn't encourage doing everything in JS, unlike React which basically forces your hand. This makes working in Vue (and Svelte) so much more accessible to people who are great at HTML and CSS but not JS as much (and in my experience many React devs are great at JS and terrible at HTML/CSS).

Designers more often know HTML and CSS over JS, so it is unlikely they are the ones pushing for JS solutions. It is the developers who don't know how to implement designs without falling back on JS for everything who are causing this paradigm.

That being said I blame a lot of this on design tooling as well. Figma and Sketch are custom rendering engines that just don't understand HTML and CSS and therefore give no opportunities for designers to learn how the web works. Fortunately a new generation of design tools are coming that are built on HTML/CSS renderers that feel like Figma but actually output usable code for devs to interpret into their projects.
