Summary of the Pull Request
Fixes a few accessibility bugs in the SettingContainer previews. Main changes include:
SettingContainerwas considered a separate UIA element from the inner expander. It's been marked asAccessibilityView=Rawto "remove" it from the UIA tree.CurrentValueAccessibleNameproperty to theSettingContainerto expose the current value to the screen reader forSettingContainers that have expanders. Non-expanderSetttingContainers already worked fine.CurrentValueAccessibleNameto various settings throughout the settings UI for full coverage. Added aCurrentValuefor the ones that were missing it.IconReferences and Relevant Issues
Paddingwas not updated since #18300 is handling that. This'll just automatically make it accessible.Font axes and features weren't updated to show previews, but I'm happy to do it if given a suggestion.
Part of #18318
Detailed Description of the Pull Request / Additional comments
SettingContainerupdates:AccessibilityView = RawforSettingContainers with expanders. This is because the expander itself is the one we care about. No need to have another layer of UIA objects saying it's a group.CurrentValueAccessibleNamepropertyAutomationProperties.NameCurrentValuechanges.Expander, if one exists."<Header>: <CurrentValueAccessibleName>". IfCurrentValueAccessibleNameisn't provided, we try to use theCurrentValueif it's a string.Icon's value is now read out by a screen reader instead of staying silent. It'll read the icon path.Icon.TabTitlenow displays/reads "None" if no tab title is set.ColorSchemeis now read out by a screen reader.Foreground,Background,SelectionBackground, andCursorColor) are now read out by a screen reader. Format is "#".BackgroundImageAlignmentis now displayed and read out by a screen reader.LaunchSizeis now displayed and read out by a screen reader. Format is "Width x Height".Validation Steps Performed
Tabbed through the settings UI with a screen reader. Each of these settings now reads out a preview.
