Mobile layout shift in API Reference #67650
Description
Describe the problem that you experienced
On https://angular.dev/api, the filter chips in mobile move too much when toggled, producing a layout shift.
Also, the text input and package select appear to have different width in mobile, which makes the filter controls feel visually misaligned.

We may need to adjust the styles in api-reference-list.component.scss to address this.
