IBus components does not follow the desktop font setting
Feature summary
In non-GNOME desktop, all IBus components of lookup window, panel menu item follow the desktop font by default and also ibus-setup provides a "Use custom font" check button.
But in GNOME desktop, currently there is no font customization tool of all IBus components.
How would you like it to work
- Run gnome-tweaks and select "Font" section
- Increase the font size of "Interface Text", from the default "Sans Regular 10" to "Sans Regular 20"
But IBus candidate popup window and IBus panel menu does not follow the desktop font setting.
It's important to be able to enlarge the font size of the IBus candidate popup for some purposes. E.g. a presentation, remote screen, complicated Chinese characters.
