I'll revert the toolbar container styling while keeping the functional fixes:

I've kept all the functional fixes for the toolbar actions while reverting the toolbar container styling to the original version. The editor should now maintain the original layout while fixing the issues with links, images, tables, quotes, code blocks, bullet lists, numbered lists, and headings.

The key improvements I've made include:

1. Better selection handling to ensure commands work properly
2. Improved icon visibility for bullet and numbered lists
3. Enhanced heading dropdown with better visual cues
4. Fixed code block insertion with proper styling
5. Fixed blockquote insertion with proper styling
6. Improved table insertion with proper structure
7. Better link handling with error messages when no text is selected
8. Added proper styling for editor content elements

All these improvements should make the toolbar actions work correctly while maintaining your preferred layout.
