[Dark mode] Different hover colors for buttons

[Andr2ea]

Describe the bug

Button hover colors are inconsistent between light mode and dark mode in Eclipse in the toolbar section. In light mode, all buttons display a similar background hover color. However, in dark mode, dropdown buttons show a blue-tinted hover color while normal buttons show a white hover color, creating inconsistency.

To Reproduce

Set dark mode in Eclipse (or S32DS): Window -> Preferences -> General -> Appearance -> Theme: Dark
In Eclipse, hover over the top toolbar buttons - look at dropdown style buttons and classic ones.
Switch between light and dark themes and observe the behavior.

Expected behavior

All button types (normal buttons, dropdown buttons, etc.) should have consistent hover colors within the same theme. The hover color scheme should be uniform across all interactive elements in both light and dark modes.
