Protected text issues

We have encountered two problems with protected text that we would like to report:

When text is marked as protected, the text is not entirely protected since it is possible to mark some of the protected text and delete or replace it.

In a table with to rows: Text in row 1 is protected. When user type in row 2 the first character typed is not shown.

Still there's the other problem where the first character is eaten by the editor if it is typed in a cell next to a protected cell.

We have bypassed that one by unblocking a space character at the end

The flag worked btw.
