What did you expect to happen? What happened instead? What would you like to see changed?

Close icon should look properly as below:

What offering/team/product do you work on? Any pressing ship or release dates we should be aware of?

cc @dakahn when you get a sec, could you confirm that this is an issue in HCM?

[dakahn]

@hnjoshi can you talk a little more about what "high contrast with white" means?

three big things we need to start triaging contrast issues of this type are browser version, operating system, and tool used for high contrast (plugin vs native).

Thanks

In Windows operating system if we choose "High contrast white" theme then we can see the problem.

Confirmed this bug on Windows 11 using the white high contrast theme

Bug not present with black high contrast theme

[dakahn]

doing a little further research it seems like our HCM styling is the culprit here. Disabling the svg fill and the X renders as expected

@dakahn does removing that line have any effect on the dark HCM / normal styles?

[dakahn]

@tw15egan yeah I assume so. We'll need to get a little MORE specific for the various themes. Something like:

@media screen and (-ms-high-contrast: white-on-black) {
    ...
}

Looks like this issue is still occurring so reopening to investigate!

Can I know when the issue could fix? Thanks.
