Lots of visual design components in Seven, Bartik, and Umami themes break when Windows High-Contrast mode is used.
Many useful design affordances are lost:
It's a user setting at the platform level - a Windows user chooses a High Contrast theme, and it applies to all desktop applications. Internet Explorer, Edge and Firefox respect this platform setting, and force similar changes upon web browser content. (Conversely, Chrome and Opera browsers do not change web content in response to this platform setting.)
The main effects of Windows High Contrast mode on browser content are as follows:
border-color is overridden, and matches the plain text or link colour, however:
border-width, border-style, and border-radius are unchanged. border-color: transparent; is overridden too. These borders become visible.outline-color is overridden, and matches the plain text or link colour, however:
outline-width, and outline-style are unchanged. outline-color: transparent; is overridden too. These outlines become visible.Text-decoration: none; is respected. currentColor is changed to match the text colour of the high-contrast Windows theme.Use individual issues to fix different components. Some will be easier than others. Commit small improvements one at a time, so Drupal gets gradually better in Windows high-contrast mode over time.
For the most part we expect to achieve this with CSS tweaks, using knowledge of the above HC effects to deliver something which works:
Screen-shot reconnaissance! Find as many differences as we can between full-colour designs and how they are rendered in windows high contrast mode.
No Changes to current visual designs, in the full-colour space.
This is about the existing designs remaining intact when using MS Windows High-Contrast mode (an assistive tech).
None.

It's likely this issue predates Contrib.social: some issue and comment data are missing.

The issue summary refers to the problem in Seven, Bartik, and Umami themes. Since 2 of those are no longer in core and there has been several years of work on Umami, is this still relevant? Are there existing issues in core for remaining problems?
