Plugin slowdown menus #11

@golubovicn

Description

@golubovicn

Dear Team,

Problem Description
When the plugin is active, navigating to the Appearance > Menus section results in a significant slowdown of the page.

Symptoms: The page starts to lag, the "drag and drop" functionality (for reordering menu items) stops working, and eventually, the entire page freezes and becomes unusable.

Testing: As soon as your plugin is deactivated, all the mentioned problems disappear, and the Appearance > Menus page functions perfectly fast and stable.

Steps to Reproduce
Enable (activate) your plugin.
Go to WordPress Admin > Appearance > Menus.
Attempt to drag and drop a menu item.

Expected Result
I expect the Appearance > Menus page to function quickly and the "drag and drop" functionality to work smoothly, even when the plugin is active.
