I just saw that since few days there is a blue color rectangle around the discussion title text field and the forum comment reply text field when typing a text.
I assume this is to show the entire space for the title or the reply text.
==> But I'm not sure if this is very useful, and it doesn't look well in my forum (dark colors) which now displays a blue rectangle.
And sometimes this blue rectangle appears only on using the space keyboard key (like with "Edit Post" option).
==> My point of view is I really prefer my forum without it !
So, is there an ergonomics reason to deploy this or is it just a bug ?
