Fix: Resolved CSS cursor and webview's cursor states conflict

Description

• Cursor within Plugin Window was flickering and conflicting with CSS styles for some elements (such as links, text elements which we can select)
• I solved the cursor flicking issue by implementing a custom display handler for the JCEF browser. Specifically, I added a CefDisplayHandler that overrides the onCursorChange method. This method updates the cursor of the browser's UI component to the appropriate predefined cursor type whenever the cursor changes within the web content. This ensures a smooth and consistent cursor experience for users, eliminating any flickering.
• Any background context or related links?
