Before this commit, when a tour tooltip was located in the snippet list, it could cause an overflow that would partly hide the tip and would bug out when being hovered. With this commit, the list is made full height, simplifying the look and giving enough space for the tip to not overflow. task-2670809 X-original-commit: d8c25d400af61bdfb4afd9d7921c3e93745f2407 Part-of: odoo/odoo#80466
