OAuth2 login dialog is unable to render a particular login screen.
Employees are following instructions on https://wiki.gnome.org/Apps/Evolution/EWS/OAuth2 to login to an organization's Microsoft provided email accounts. Evolution presents organization OAuth2 window but it is blank. Url field shows correct OAuth2 provider URL. Epiphany browser, which supposedly uses identical WebKit, has no problems rendering the same organization login page. Tested on latest available from flatpak on Fedora 39 as of now: 3.48.4 (3.48.4-1.module_f38+17164+63eeee4a) and several previous.
