I see a lot of "IInputPane2::TryHide is failure" warnings while WPT for editing API runs. According to MSDN, they return true only when the application is foreground and the input panel hasn't been the requested state yet. Therefore, it should check whether the foreground window is our process or not, and whether the input pane state is expected or not before warning. * https://docs.microsoft.com/en-us/uwp/api/windows.ui.viewmanagement.inputpane.tryshow?view=winrt-18362 * https://docs.microsoft.com/en-us/uwp/api/windows.ui.viewmanagement.inputpane.tryhide?view=winrt-18362 Differential Revision: https://phabricator.services.mozilla.com/D76295
