Clicking inside the task pane content and immediately scrolling over the worksheet causes Excel to become unresponsive

问题

Steps to reproduce:

1. Click anything inside the task pane content.
2. Move the mouse over the worksheet (do not click anything).
3. Scroll with the mouse wheel over the worksheet.
4. Notice that Excel becomes unresponsive.
5. Minimize then restore Excel. Notice that Excel becomes responsive again.

I was able to reproduce this with the basic Excel Add-in project template in Visual Studio.

I'm currently using the latest build of Excel (16.0.7726.1030).

Any workarounds?

Thanks!

I'm able to replicate this using Visual Studio 2017 and Excel 2016 for Windows but only when launched from within Visual Studio. When loaded outside of Visual Studio (i.e. side-loaded into Excel) it no longer exhibits this behavior.
