Steps to reproduce

Use TabsCount (without setting forceMount) with multiple tabs and then switch between them in an SPA; inspect the DOM, they're all there.

Describe the bug

TabsContent hardcodes force-mount when calling presence.

Introduced in commit 9526356 - looks like it was intended to hydrate tab content for SSR, but it's breaking change for SPA.

Expected behavior

Detect if we're in SSR or SPA mode and honour force-mount prop on TabsContent.

Code should read :force-mount="!isBrowser || forceMount"
