i looked in to it some more and i'm pretty sure it's a bug in the wysiwyg editor that ships with mybb.
it's possible to replace this editor with another one using a plugin, for instance https://community.mybb.com/mods.php?action=view&pid=657
i've tested that one locally and it works fine with your post sample.
