Description

Moving AB#1100128 to GitHub

"This is happening because the text view used to enter Breakpoint Conditions does not implement IWpfTextView2. This interface defines method QueueSetFocus whose implementation is necessary to fix this bug. The text view in question is Microsoft.VisualStudio.LanguageServices.Implementation.DebuggerIntelliSense.DebuggerTextView which is owned by Roslyn."

Research direction
The issue is about implementing the IWpfTextView2.QueueSetFocus method in the DebuggerTextView class located in Microsoft.VisualStudio.LanguageServices.Implementation.DebuggerIntelliSense. The problem is that the text view loses focus after clicking completion filters. To fix this, you need to understand the IWpfTextView2 interface and implement QueueSetFocus appropriately. Look at the Roslyn codebase for existing implementations of similar interfaces as a reference.
