Description

Overrides the FlowDirection of the ColorSpectrum to be LeftToRight regardless of parent FlowDireciton

Current Behavior

ColorSpectrum.FlowDirection will be inherited from its parent, resulting in a mirrored view when RightToLeft

New Behavior

Unless explicitly set to FlowDirection.RightToLeft, the ColorSpectrum will remain LeftToRight and the color spectrum will not be mirrored.

How Has This Been Tested?

• I have performed a self-review of my own code
• I have added tests to cover my changes

I have not tested the code with this change. I'd appreciate help setting up a test environment. This is a very simple change though.

@Jay-o-Way I have not seen one, no But I would gladly hash it out. Can we pull any other RTL language speakers in here? I can advocate with high confidence that Hebrew speakers would not expect this to be mirrored, and with slightly lower but still in fair confidence that Arabic is the same.

Here's a similar discussion from microsoft/calculator

As a native Hebrew speaker, RTL is about written language, and maybe a bit about layout related to text.

Flipping anything else is gonna be highly frustrating, I'll give an example of such bug seen on some cellphone, the clock changes its layout on RTL, hence could write 55:11

Regarding the color palette, as one that uses a graphic tablet on a weekly basis.

My muscle memory doesn't know if it's RTL or not, and do consider flipping it as a bug

As a native Arabic speaker, I can agree that this element should be kept left-to-right; mirroring it does not provide any real benefit.
