Formatting goes plain when I use Find & Replace in Calc

Everytime I use “Find & Replace” in Calc, every inside cell formatting disappears.
For instance, imagine I have this text (sorry it’s Portuguese, but I think you’ll get it):

Then, I want to replace “palavra” by “X”.

It is replaced, but all the bold letters are changed to plain text.

Am I doing anything wrong? I’m using version (x64).

See #tdf38982 -Calc [EDITING, FORMATTING] find & replace causes default formatting to be applied to cells, undo working incorrectly (the undo thing seems to be fixed but the formatting issue still is reproducible).
