Flyout displays incorrectly with FlowDirection set to RightToLeft

[ORRNY]

Describe the bug

When setting the FlowDirection property of a Window to RightToLeft in a WPF application using UI.WPF.Modern, the Flyout component is positioned incorrectly.

Expected behavior:
The Flyout should appear at the correct location corresponding to its anchor, even with RightToLeft flow direction set on the Window.

Actual behavior:
The Flyout appears in an incorrect position. Please see the attached screenshot for visual reference.

Reproduction

To reproduce:

• In the WPF.Modern.Gallery project, set FlowDirection="RightToLeft" on the main Window:

  <Window x:Class="iNKORE.UI.WPF.Modern.Gallery.MainWindow"
  ...
  FlowDirection="RightToLeft">

• Navigate to a page containing a Flyout. The Flyout will be displayed at an incorrect position (see the screenshot).

Alternatively:

1. Create a new Window and set FlowDirection to RightToLeft.
2. Add a Flyout component.
3. Open the Flyout – it will appear in the wrong position.

Suggested Solution

I do not know the exact solution, but it may require adjustments to the Flyout's position calculation when FlowDirection is RightToLeft.
