JSON Editor Becomes Read-Only After Using "Find and Replace"

[keeganedwin]

Describe the bug
When editing tokens in the JSON editor within the plugin, using the Find and Replace functionality causes the editor to enter a read-only mode. Users can no longer make any changes until they close and reopen the plugin.

To Reproduce
Steps to reproduce the behavior:

1. Open the Tokens Studio plugin and navigate to the JSON editor
2. Use the "Find and Replace" feature (e.g., ⁠Cmd+F or ⁠Ctrl+F)
3. Enter a keyword to find and a term to replace it with
4. Execute the replacement
5. See error

Expected behavior
The JSON editor should remain fully editable after a "Find and Replace" operation is completed. The act of finding and replacing text should not trigger a read-only state.
