Description

When two USelectMenu components are on the same page and the first is open, clicking the trigger of the second one causes it to open for a split second and immediately close.

Regression: Works correctly in @nuxt/ui@4.6.0. Broken since 4.6.1.

Workaround: Pin @nuxt/ui to 4.6.0: "@nuxt/ui": "4.6.0" (without ^)
