newlines doens't work in figtable multiline cells

[emiltin]

Hi,
In normal RST simple tables, you can have several lines in a cell, usign plain line breaks. In https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#simple-tables this example is provided:

=====  =====
col 1  col 2
=====  =====
1      Second column of row 1.
2      Second column of row 2.
       Second line of paragraph.
3      - Second column of row 3.

       - Second item in bullet
         list (row 3, column 2).
\      Row 4; column 1 will be empty.
=====  =====

But this doesn't seem to work with figtables. It only works if ´|br|` is used instead of newlines?
