Description:
When doing a search and replace (of italics in my case) in a cell, if one undoes the changes, reapplies them and undoes them again, the whole formatting of the cell disappears. 

Steps to Reproduce:
1.Apply search and replace (3 times for ex.) in a cell where italics (for ex.) are present (file provided below)
2. Undo the replacements
3. Redo the replacements
4. Undo them 

Actual Results:
At this point the formatting of the cell disappears.

Expected Results:
Everything should remain the same except what is concerned by the search and replace undo and redo.


Reproducible: Always
