Problem with live view setting when hiding the screen

[gullradriel]

When using the 'hide screen' feature, the live view option is correctly deactivated on first use, but not after a page refresh / browser reload.

The effect is visible as when first activation "hide screen" the control buttons are super responsive and not redrawn, but after a refresh / browser reload, they are grayed out and recolored after a second, at each click.

Please check that live view is correctly disable when "hide screen" is in use, even after a refresh / browser reload.
