During the OWL refactoring, the "decoration-bf" and "decoration-it" were not included in the standard decoration handling to convert them into the default bootstrap classes. I.e. the previously applied commit: https://github.com/odoo/odoo/pull/73210/commits/29390ccdc3447c3d1ef4da1d805e630d00402fbd was not ported over to the updated OWL views/fields. Note that this commit uses the BS5 classes of fw-bold and fst-italic and should not be backported because of that. Also added QUnit tests to handle these 2 decoration cases. closes odoo/odoo#99698 Signed-off-by: Aaron Bohy (aab) <aab@odoo.com>
