Connor McAdams : uiautomationcore: Don't use nested node providers for same-thread HWNDs.
Module: wine Branch: master Commit: 63814b70d1f6f16640179b07eb5ea8a7c80e713d URL: https://gitlab.winehq.org/wine/wine/-/commit/63814b70d1f6f16640179b07eb5ea8a... Author: Connor McAdams <cmcadams(a)codeweavers.com> Date: Thu Sep 15 11:28:00 2022 -0400 uiautomationcore: Don't use nested node providers for same-thread HWNDs. When a client requests an HUIANODE for an HWND that belongs to the same thread, use an IRawElementProvider based provider rather than an IWineUiaNode based provider.
