ActionList: Fix leaky disabled description styles

[siddharthkp]

• Reported in https://github.com/github/collaboration-workflows-flex/issues/927

Problem

Description in a disabled item should not have color: fg.muted but the disabled color. We set this by adding the disabled color on the item and adding color:inherit on the description. Source

conststyles={'li[aria-disabled="true"] &': {color: 'inherit'}}return<Boxas="span"sx={styles}/>{props.children</Box>

This feels safe because we are only targeting Description inside li[aria-disabled=true]. This is the generated css:

li[aria-disabled="true"] .Box-sc-g0xbh4-0 {
color: inherit;
}

The trouble here is that the generated className for '&' is not the className just for ActionList.Description but is passed to multiple elements within ActionList.Item. 🤔

This really threw me off!

Solution

As a quick fix, I added a data-component to make the selector more specific. Expecting no visual changes, only changes in the generated css.

Before	li[aria-disabled="true"] .Box-sc-g0xbh4-0 { color: inherit; }
After	li[aria-disabled="true"] .Box-sc-g0xbh4-0[data-component="ActionList.Description"] { color: inherit; }

@siddharthkp wanted to ask if this is possible to capture in VRT or nah? (Or is it already?)

Maybe but not a clean one. The instance where this happens in gh/gh is also not the best use case for ActionList
