examples of (mis)aligned cells

OOO330m18 (Build:4) tag libreoffice-3.3.0.2
Spreadsheet application:
Precondition: An arbitrary cell shall contain 2 lines of text.
Alignment is left, bottom, 0 degrees.
Line heigth should be longer than text length.
Execute: change cell format "<ctrl>1", alignment and change angle to 90.
Expected: text is rotated 90 degrees counter clockwise beginning at the bottom of the cell.
Actually the text seems to be left-end-aligned with the beginning governed by the longer of the two lines.
Workaround: if the angle is 89 or 91 degrees or if the cell contains only one line of text the behaviour is as exected.
With different preconditions : Alignment left, top, 0 degrees
the text seems to disappear at 90 degrees.
