[Issue] theme colour selector does not update when importing theme

[Magicmaan]

found in desktop app, latest release version

when importing a theme, the colour selectors for theme does not update to the current, instead being what it was before the theme was imported.
this means pressing the X button to cancel, will default the colour to old one, instead of what the theme set it to.
along with this, if the theme is then reset to default and the colour selector is open, the theme colour is set to that of selector
