[FIX] website: prevent CTRL-K from focusing on browser's URL bar

Ever since the website is previewed in the iframe [1], pressing CTRL-K
(or Meta-K on macOS)  while previewing the website can result in
focusing on the browser's URL bar on top of summoning the command
palette.

Steps to reproduce:
- Preview the website
- Click on the iframe to focus on it
- Press CTRL|Meta - K
- URL bar is focused

This commit fixes that by preventing the default behaviour within the
iframe and only summon the command palette.
