Screencast of being unable to switch among Excel windows

I'm running Mint Cinnamon 18 and I see a bug similar to #23108:

If I open two spreadsheets in Excel 2007, I can't reliably switch among them
using Alt+Tab. Alt+Tab appears to have switched, but the old file still has
focus. Clicking on the taskbar icons does nothing. The first Alt+Tab works, but
subsequently using the shortcut doesn't. Alt+` (cycling only through Excel
windows) doesn't work either.

This is super frustrating for those using more than one spreadsheet at the
time.
