### Issue description

Whenever the tileset property of any tilemap node is like open in the editor like this:

If I select any other node and then select the TileMap node again it will print this error:

` editor/editor_node.cpp:8152 - Condition "plugins_list.has(p_plugin)" is true.`

This seems to be actually true to any plugin or `EditorInspectorPlugin` that edits node. In my project I have a InspectorPlugin that adds some buttons in `_parse_begin` for a specific kind of node, and that node also has an exported custom resource, and whenever I select any of that Node and their resource is open for edit in the Inspector I get the same error.

### Steps to reproduce

- Create a TileMap node on any scene
- Create a new TileSet resource on the TileMap node
- click on the TileSet resource to edit it in place in the TileMap node
- Select any other node
- Select the TileMap node again.

- Open main scene
- Select the TileMap node
- Click the tileset resource in the inspector
- Select the root node
- Select TileMap node again
