Commit https://github.com/odoo/odoo/commit/903ff171acbef7f9fe6e533f43b99eba801b200f lowered the font-size to 14px for the frontend by customizing the bootstrap variable in the portal app. It changed the web_editor rte_inline tour accordingly. This however broke the test on runbot "base" database, as the font-size in the editor without having installed the portal app was still set to 16px. Commit https://github.com/odoo/odoo/commit/e3bc059c3649a05c12cd3c8099092282c10141b7 only moved the failed test from "base" to "all" database. This commit unifies the font-size for all frontends by setting it in the web app. So, after this commit: reports, editor, login screen and frontend will always have a font-size of 14px no matter the application which is installed (except themes).
