path.Join is for file paths, which will call path.Clean and malform the path by converting double slash in front of the authority in a URI into a single slash.
The workaround is to parse the URI, then join the path bit.
One day I will encapsulate all that.
Some relevant bits for when I write that encapsulation:

What’s the deal with those white oval-shaped bumper stickers? Good question! The usage of these white oval decals originated in Europe in the early 20th century.

Cool: a Packer template for Alpine Linux on Hyper-V and Azure: [WayBack] GitHub – tomconte/packer-alpine-azure
I like Alpine Linux because it is lightweight and the focus of being very secure, how popular it is in the Docker scene where it replaced Ubuntu and is now the standar package at [Archive.is/A2] library/alpine – Docker Hub and the motto [WayBack] Alpine Linux; Small. Simple. Secure. Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busybox.
Alpine is not yet out of of the box endorsed by Azure ([WayBack] Endorsed distributions of Linux | Microsoft Docs) so this is a very welcome tool.

Below some links I used to get a feel for the different query execution plan entries I observed.
The first one was the most important for me, so hopefully this post helps bump it up in the search engine results.

A feature overlooked by many Delphi programmer was already introduced in Delphi 1 which is more or less the same as in the Delphi 2007 documentation at [WayBack] Type Compatibility and Identity.
There is a distinction between these explained in the above link:
type TMyInteger1 = Integer; TMyInteger2 = type Integer;
Where TMyInteger1 is an alias for Integer, TMyInteger2 introduces a new type which is distinct from Integer and TMyInteger. That way the compiler can set them apart, and even generates separate RTTI (Run-Time TypeInformation) for them.
Probably the most used distinct types are these:
TDateTime = type Double;
...
TDate = type TDateTime;
TTime = type TDateTime;
TFontName = type string
These are unlike TColor which is defined as “just” a subrange of Integer, but because it is a subtype, also gets a distinct type:
TColor = -$7FFFFFFF-1..$7FFFFFFF;
Type identity is important because Delphi 1 introduced these mechanisms:
Without them, very basic Delphi features would not work.
In addition, a lot of other RTTI based code now enables features like object relational mapping, binding to JSON/XML and many others.
What I did not know is that the Pascal and Delphi type systems have been heavily influenced by ADA. Luckily Lutz Donnerhacke pointed me to ADA [WayBack] Types and Subtypes.
I made an example Distinct type types in Delphi · GitHub showing the differences on RTTI level in these properties:
property IntegerProperty: Integer read FIntegerField write FIntegerField;
property ColorProperty: TColor read FColorField write FColorField;
property DoubleProperty: Double read FDoubleField write FDoubleField;
property DateTimeProperty: TDateTime read FDateTimeField write FDateTimeField;
property DateProperty: TDate read FDateField write FDateField;
property TimeProperty: TTime read FTimeField write FTimeField;
property StringProperty: string read FStringField write FStringField;
property FontNameProperty: TFontName read FFontNameField write FFontNameField;
The generated table (see also the source below using [Archive.is] TRttiContext added in Delphi 2010) indeed shows distinct types on the RTTI level:
NameType.NameType.QualifiedNameType.TypeKindIntegerPropertyIntegerSystem.IntegertkIntegerColorPropertyTColorSystem.UITypes.TColortkIntegerDoublePropertyDoubleSystem.DoubletkFloatDateTimePropertyTDateTimeSystem.TDateTimetkFloatDatePropertyTDateSystem.TDatetkFloatTimePropertyTTimeSystem.TTimetkFloatStringPropertystringSystem.stringtkUStringFontNamePropertyTFontNameSystem.UITypes.TFontNametkUString
