Before this commit, Defining action using <a type="action"> outside of normal views(like qweb view) css style does not apply to it because missing the href tag. by defining href tag on a link will first open home screen then perform do_action thus it will do flickering. After this commit, Prevent event default behaviour so it will stop flickering and restore css style for action by defining href tag on it. closes odoo/odoo#33703 Signed-off-by: Aaron Bohy (aab) <aab@odoo.com>
