Button toggle states "on" and "over" not obvious on default dark theme

[OlivierJaquemet]

Toggle state is described in the Eclipse UI Guidelines :
https://eclipse-platform.github.io/ui-best-practices/#toggled_states

When using the default light mode theme, the "on" and "over" states are quite obvious.

However, when using the default dark mode theme, the "on" and "over" states are almost indistinguishable from the "off" states, as seen in thefollowing captures which demonstrate the issue using the Scroll Lock button of the Console view.

Scroll lock - toggle state - OFF state :

Scroll lock - toggle state - OVER state :

Scroll lock - toggle state - ON state :

PS :

• I could not change the behavior using the OS settings
• I would like the default Eclipse installation to be provide the best behavior and that's why I don't want to install plugin from the markeplace to fix this
