Subject: [PATCH] [FIX] web_editor: fix HTML/CSS editor resizing bug

Starting on version 16.0, the HTML/CSS editor is very hard to resize.
This is due to 16.0 introducing an iframe for the website: as soon as
your mouse enters the iframe, the editor loses focus and cannot be
resized anymore.
This commit fixes that.
