Bug: Datatable pagination issue on Firefox(?)

[Lakelimbo]

Describe the bug

It seems like the pagination on both docs and the guide on the Data Table component have a weird bug (apparently specific to Firefox?), where you can't properly paginate between pages. Whenever clicking to go to the previous or next page, the index jumps by 2 or 3 numbers, eventually even going out of bounds (non-existing page).

Reproduction

Go to either the Tasks or the dashboard 01 block (pnpm dlx shadcn-svelte@latest add dashboard-01) and try to go to the next or previous on the table on Firefox. I am not able to reproduce this issue on Chromium.
Originally I thought it may have been an upstream issue with Tanstack Table, but the issue seemingly does not occur on the original Shadcn/UI's tasks datatable.

Maybe this is an extension or something? Trying this in the firefox based Zen browser I am not able to reproduce.

Same here now. Seems to be resolved? Either by some PR or a Firefox update. Maybe related to huntabyte/bits-ui#1638
