/*! The popover is opened directly by the GTK surface,
|
|
without bouncing click events off the main state.
|
|
Then it must accurately show which layout has been selected.
|
|
It can get the system layout directly from gsettings on open,
|
|
but it cannot get the user-selected overlay, because it's stored in state.
|
|
|
|
To solve this, overlay will be cached in the popover actor,
|
|
and updated by main state every time it changes.
