[Bug]: OOBE · theme editor · cannot select/apply themes

[PaulCoddington]

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

Selecting a theme has no effect on a fresh OOBE installation until at least one theme has been saved.

Steps to reproduce the problem

1. Select any theme in theme editor (it has no effect).
2. Click the Save button for any theme.
3. Reload WebUI.
4. Select any theme (theme selection now works).

What should have happened?

Theme selection should work at all times, even when themes have never been modified or saved.

What browsers do you use to access the UI ?

Microsoft Edge

Additional issues:

• Theme editor colors are not loaded from selected theme (default to 0,0,0).
• Color selector popup swaps R and G values on save.
• Cannot set hover/infotip text and background colors.

Workaround:

Create and edit theme files in text editor.
