WM_NCHITTEST returns HTCAPTION for client area and tabs

[chaohershi]

Description of the new feature/enhancement

Please consider placing the tabs into the client area instead of the title bar. Right now the tabs are in the correct place only with setting "showTabsInTitlebar": false,. This will cause problems with softwares that utilize the title bars.

Default settings

"showTabsInTitlebar": false,

Proposed technical implementation details (optional)

Take a look at Edge browser. Edge used to place everything in the title bar as well, but now it has been fixed.

Well, that's certainly an interesting one. Thanks for finding this!

I've updated the title to more accurately represent what is happening.

Offending code is in NonClientIslandWindow.cpp, NonClientIslandWindow::_OnNcHitTest.
