If a script replaces the whole content of a textarea, this is recorded in the undo stack. When this change is undone, the whole content is selected, no matter what the selection was before the script did its change.

Reproducible: Always

Steps to Reproduce:
1. Open attached test file.
2. Type 'abcdef' into the textarea.
3. Select 'cd'.
4. Press Ctrl+9. (The selected characters are enclosed in parentheses: 'ab(cd)ef'.)
5. Invoke the Undo function.
Actual Results:  
The textarea content is restored to 'abcdef', the way it was before step 4.
The whole content is selected.

Expected Results:  
The textarea content is restored to 'abcdef', the way it was before step 4.
The letters 'cd' are selected, the way it was before step 4.
