Is it possible to prevent the browser tab from closing when I exit Vim?

[`let g:mkdp_auto_close = 0`](https://github.com/iamcco/markdown-preview.nvim?tab=readme-ov-file#markdownpreview-config) didn't work.

## Wanted Behavior

- IS NOT: Even after exiting Vim, the server keeps running.

- IS: After exiting Vim, the server stops, but the browser tab remains intact (of course with no refreshing anymore).

## Use-cases

I sometimes want to keep reading `README.md` or Markdown documentations even after closing Vim.
