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?
