Remove STABILIZE_DELAY from UIA consoles. (#12679)
During initial development of UIA in consoles, I added the STABILIZE_DELAY present in the legacy console support for consistency across implementations. However, the delay seems to offer no practical benefit to UIA and appears to contribute to lag.
Description of how this pull request fixes the issue:
Removed STABILIZE_DELAY from the UIA console. Legacy console users (i.e. the current default experience) are completely unaffected.
