This fixes a bug that occurred when using BACKSPACE to remove the last character of a text node, if said character was preceded by a space and said text node was succeeded by a <br>. The space was removed along with the character. This was simply due to a missing state restoration rule to handle this specific case. task-2990229 closes odoo/odoo#102974 X-original-commit: 5e90529388095321da8b504ebf543c4c3054845e Signed-off-by: David Monjoie (dmo) <dmo@odoo.com>
