The TextBlock TextAlignment enumeration contains duplicate entries.

[johnt-star]

Describe the bug

Not sure if this is a bug or by design, but the TextAlignment enumeration used by TextBlock contains the duplicate entries.

Using Enum.GetValues shows there are 7 entries in total.

There are 2 entries labelled Left and 2 entries Labelled Right.

Screen capture below lists all entries.

Steps to reproduce the bug

See attached code.

Use Enum.GetValues to retrieve and display TextAlignment members.

Expected behavior

Entries should have unique names in order to distinguish between the entry's behavior.

Screenshots

This is the list showing the duplicate names:

This is a breakpoint in the code showing duplicates. Note that the entry "Right" shows up as "End", but is still duplicated.
