Cancel button on updates page is broken
Cancel button on updates page is broken with gnome-software-3.30.5-1.fc29. There are two problems:
- It doesn't actually cancel anything. Application updates continue to install for a long time after the button has been pressed.
- The style is broken. The below screenshot shows a sensitive Cancel button that has not yet been pressed. It looks insensitive (bad!) but note that the foreground text is dark black, like a sensitive button. So the style is halfway between sensitive and insensitive. When pressed, the text color changes to match insensitive text color.
