Edge: Inherit dark theme from Eclipse - regression

[reinholdk]

Describe the bug
MS Edge based browser controls are inheriting dark/light theme from OS instead of respecting the Eclipse theme settings.
This was fixed earlier in the scope of #1529 but reoccured with newer Windows/Edge versions.

To Reproduce

1. Switch on dark mode for apps in Windows settings
2. Set Light theme in Eclipse preferences
3. Restart Eclipse
4. Edge based Browser views render in Dark mode. Rest of Eclipse is Light.

Can be reproduced by opening any Browser based view (Help Contents, Java Tooltip - F2, ...).

Expected behavior
Browser based controls inherit the theme configured in Eclipse preferences.

Screenshots
black scrollbars in tooltip are indicating that Dark mode is used

Environment:

1. Select the platform(s) on which the behavior is seen:

• • All OS
• • Windows
• • Linux
• • macOS

2. Additional OS info (e.g. OS version, Linux Desktop, etc)
   Windows 11 23H2
   MS Edge 1.42

3. JRE/JDK version
   21.0.8

Version since
Independent of Eclipse version

Workaround (or) Additional context
Use same mode (Dark/Light) on OS and Eclipse

I have debugged the Edge.setupBrowser method. Looks like profile.put_PreferredColorScheme is called with the correct value but has no effect.
