Preview hard to exit on wayland

[stefonarch]

If a theme preview is shown on wayland the "close preview" button is behind the preview, ESC doesn't work and only way to exit the preview is to use the window switcher to bring the "close" window in front.

Configuring ESC to close preview would fix it, otherwise layer-shell-qt is needed to put the "close" window in overlay mode.

Thank you! What do you think if we remove the button, and use only Esc by adding a label "Press Esc key to exit the preview."?

Like in Sqreenshot area selection (was LxImageQt screenshot tool code), but maybe better if with a transparent background (here black opaque)

Easy solution ;)
