Description

Details element gets styled very close to Details component with many of the enhancements, just the hover affordance is missing for this plan HTML5 use case. This sets the cursor to pointer, as the full component does.

• I have documented this change in the design system.
• I have recorded this change in CHANGELOG.md.

Issue

Resolves #948

Testing

1. I have not fenced this behind any @supports not (-ms-ime-align: auto) of sorts for things like IE that don't provide the functionality as that adds extra cruft (and false positives) for not much benefit, when MzpDetails actually provides a polyfill for such browsers.
2. I have opted for a plain extra declaration instead of the @summary mixin (which gets included within half a dozen of things) not to apply such styling to places that render it own ways.
