Document more visibly how to set the iframe to full width

[Marc-pi]

The issue
by default, the iframe window is not full displayed on width size
Tested with FF and Chrome

Impact
Gutenberg makes use of several panels, with such a shorter width it is difficult to play / test it

using seamless mode will allow having full width.

ok, did not notice this option , thx
would be worth to be added in the FAQ https://wordpress.github.io/wordpress-playground/faq
and/or maybe there https://wordpress.github.io/wordpress-playground/start-using

it's part of Query API and documented here https://wordpress.github.io/wordpress-playground/query-api

Thank you for reporting Marc-pi! The documentation could use a structured redesign – I'll mark this issue as an enhancement so it comes up when that project starts.
