UC脚本在141上部分失效

/* Restore 'Space & Separator' items script for Firefox 102+ by Aris
   
  Default browser scripts always remove spaces and separators from default palette, so
  because of that they are added to an own toolbar now.
   
   - spaces and separators can be moved to any toolbar
   - to remove spaces or separators move them into palette
   - configuration toolbar behaves like a default toolbar, items and buttons can be placed on it
   - configuration toolbar is not visible outside customizing mode
   - default "Flexible Space" item is hidden from palette and added to configuration toolbar
   [!] BUG: do not move spaces, flexible spaces or separator to configuration toolbar or it will cause glitches
   [!] BUG: do not move main 'space'-item to palette or it will be hidden until customizing mode gets reopened
   
   [!] Fix for WebExtensions with own windows by 黒仪大螃蟹 (for 1-N scripts)
