@Sekar47 we're investigating in our internal designer repo. We'll update this when we have an investigation.

@Sekar47 this is on our backlog, but I don't have an estimate for when we'll have a fix.

That said, we have confirmed that you can access the desired tab directly if you select it via the PropertyBrowser or DocumentOutline windows in Visual Studio. Given that there are multiple ways to get to any TabPage that you need, it may take us just a little longer to address this specific issue.

@Sekar47 - mouse click is processed by the VisualStudio process and is forwarded to the DesignTOolsProcess as an input message to be processed by the corresponding ControlBodyGlyphs. https://learn.microsoft.com/en-us/dotnet/desktop/winforms/controls-design/designer-differences-framework?view=netdesktop-8.0 Also see samples here - microsoft/winforms-designer-extensibility
