Before this commit* the flex parent of the discuss element was no longer in the `column` direction, which caused an overflow in some of its children elements, like the topBar and the composer. This commit fixes this issue by setting the `flex-direction` of the discuss parent to its former value. * since https://github.com/odoo/odoo/commit/cbe1bc809538f690115e1632448258663e1f52e4 closes odoo/odoo#84290 X-original-commit: f902efa94baed8d0bf5aae6f4314891c5c2b57a1 Signed-off-by: Sébastien Theys (seb) <seb@odoo.com>
