I'm using a vanilla Sitecore 82u6.
When checking the .showconfig.aspx page I realized that the default language name is:
<setting name="ClientLanguage" value="en" patch:source="Sitecore.DefaultLanguage.config"/>
On the Sitecore.Globalization.LanguageDefinition class, the name property is defined by the following logic:
this._name = id + (!string.IsNullOrEmpty(this._region) ? "-" + region : string.Empty);
But if we look at the LanguageDefinitions list on the same page, we can't find a language with this name

That means that if you parse each one of the above language definition names using
LanguageDefinitions.Definitions.Select(definition => Language.Parse(definition.Name));
None of them would be equals to
Language.Parse("en")
Since the Language.Equals(..) uses
language1.Name.Equals(language2.Name, StringComparison.OrdinalIgnoreCase);
Do you guys know what I'm missing here? I'm pretty sure that one of my assumptions here is not correct since that OOTB setup works properly.
