Desktop: Phosh on a 4k screen
Element-desktop cannot be resized like other windows. This is the only app that I have seen so far with this issue.
Super + arrow keys move the small window around but don't change the size.
Super + right-clicking a corner fails to resize the app as well.
Super + left-clicking works to move the window but tends to make the app jump to the wrong place the first time you move it.
