Map Layers widget options do not meet WCAG accessibility standards?

[BMCGIS]

I'm using the WebAIM browser plug-in to check the accessibility of an Experience Builder app. I am getting an error for "very low contrast" for the Map Layers widget, meaning it does not meet the 1.4.3 Contrast (Minimum) (WCAG 2.1 Level AA).

From what I can determine, this widget doesn't allow any specific color configurations and is using the Container and Selected colors from the theme, which I have not changed from the Prime theme defaults.

In my app, I get this error whenever I have this widget active, no matter what options are enabled in the configuration.

Then I built a simple app to try to reproduce this error. On one app page I have the Map Layers widget with some options enabled and WebAIM does not find any contrast errors (so this is different behavior from my app). On another app page I have checked the option for Enable layer batch options, and this gives the same "very low contrast" error.

Has anyone else encountered this? Are there any modifications I can make or should this be reported to Esri as an issue?

Hello @BMCGIS 

Your app examples are not public, so I cannot view them.

If you click Customise in the theme settings, you can configure your widget theme colours.

You may log an accessibility enhancement if you wish for this to be considered in future releases of ArcGIS Experience Builder. Create a technical support case in My Esri to initiate the enhancement process.

@EMani Oops, thanks. I changed the test app to public.

I also changed the theme colors to white Container background, black Container type, black Selected  background, and white Selected type for maximum contrast. However, I still get the same error.
