When converting the list view to owl, the caret indicator for groups in list view was incorrectly given the extra class `fa-fw` which gives the icon a fixed-width. This is incompatible with using padding as spacers, and caused the caret to overlap the group name in nested groups. This commit fixes that by removing the `fa-fw` class. closes odoo/odoo#106994 X-original-commit: ff1055ddd07653d156a5887081f3ebe22dcbcae0 Signed-off-by: Samuel Degueldre <sad@odoo.com>
