Grid layout with 100% width shows only 10 variants

### Describe the bug

In grid layout with 100% width the maximum amount of variants is not updating/showing correctly and the story only shows first 10 variants. Resizing the window sometimes helps and update/show more variants.

### Reproduction

I took the `histoire-vue3-starter`, updated `histoire` and `@histoire/plugin-vue` to latest version `0.12.4` and created a simple `MaximumVariant` story with 15 variants. https://stackblitz.com/edit/histoire-vue3-starter-ntbrzs?file=src/MaximumVariant.story.vue. Scrolling down only shows 10 variants.

Start with the linked histoire-vue3-starter reproduction and inspect the grid layout's variant rendering and resize handling. Confirm the behavior with a 15-variant story; done means all variants appear at 100% width without requiring window resizing.
