A11y_VSUserStory935073-ContainerToolsWindow_ AddContainerOrchestratorSupport_ScreenReader:Narrator announces space unnecessarily for the "ok" button at the end. #2409

This issue is not observed with NVDA.
By design for WPF. Narrator announces a control's AccessKey if it has one. Setting Button.IsDefault=true sets the button's AccessKey to "\x0D" (ENTER). Narrator chooses to announce this as "space". That's Narrator's decision, Inspect shows the automation AccessKey property set correctly to \x0D.
WPF is exposing the AccessKey to automation correctly.
