Performance drops when working with protected document that has unprotected section

Question

Hello, huge fan of the Blazor Document Editor. Very developer friendly!

To reproduce this issue,

Prep word doc

Open a word doc of any text in edit mode.
Go to review tab and click Restrict Editing
On the Restrict Editing pane, check Allow only this type of editing in this document:
Ensure No changes (Read Only) is selected on the dropdown
Highlight an area of text in the document.
Check off Everyone in the Exceptions (optional) section to allow users to only edit this text selection
Click Yes, start Enforcing Protection
Click ok in dialog because no password is needed
Save this word document.
Open the file in a Blazor Syncfusion Document Editor. The document should be read only mode, but the unprotected section is highlighted. Everything works as expected, and the user can edit in the unprotected section. However, the entire editor behaves very slowly. This is likely because it is running some task to check whether a section is protected or unprotected and this is blocking the single Blazor thread which runs the UI. This is probably being called each time the user makes a keystroke.

Hello, thanks for your reply.Confirm whether you are usingBlazor server or web assembly app?I am using a combination of the two for this app, but the document editor is in a Blazor WebAssembly App.Document editor version details.Nugetpackage: Syncfusion.Blazor.WordProcessor 20.1.0.50If possible, share the document which you have tried at your end.Example document with protections in place is attached.When opening in syncfusion doc editor, you should be unable to edit anything besides the second paragraph which is highlighted.When editing the highlighted area, it is very delayed but still works.
