Toast UI Editor: Selection/Cursor jumps to beginning after applying color with custom plugin

Problem

I'm using Toast UI Editor with the color syntax plugin. When I apply a color to selected text:

1. Issue 1: The cursor jumps to the beginning of the line/paragraph (only on first color change)
2. Issue 2: When changing text to the same color or partially changing color, the highlight still displays

Environment

• Toast UI Editor: [version]
• @toast-ui/editor-plugin-color-syntax: [version]
• Browser: [browser + version]

Expected Behavior

• Selection/cursor should remain at the end of selected text after color is applied
• Changing to same color should remove the color (not display highlight)

Actual Behavior

• Cursor jumps to beginning of line after applying color (first time only)
• Highlight background still appears even after changing to same color

Attempts Made

1. Tried setting tr.setSelection() before and after dispatch
2. Tried saving/restoring selection using editorNode.getSelection()/setSelection()
3. Tried wrapping dispatch with setTimeout
4. Tried calling original command instead of custom implementation

None of these approaches solved the cursor jumping issue.

Question

• How can I prevent the selection from being reset after the color command?
• Is there a proper way to handle selection preservation in Toast UI Editor plugins?
• Should I use a different approach (hooks, events, etc.) instead of overriding the command?

Any insights would be appreciated!
