Steps to reproduce the problem:
1. Open new window
2. Navigate to any page in first tab
3. Open a second tab (Command-T)
4. Switch back to first tab
5. Command-W to close the first tab
6. Command-Shift-T to undo close tab

What is the expected behavior?
The previously open tab should be re-opened.

What went wrong?
A new "home" tab is opened as if I had used Command-T (without shift).

Did this work before? N/A

Command-Shift-N fails to open an incognito window, instead just opening a regular window as if I had pressed Command-N.

Command-Shift-B appears to work correctly however. Perhaps because there is no Command-B shortcut?

Order of pressing Command and Shift keys does not matter.

Note in the Dvorak layout that none of these keys (T,N,B) are the same between Qwerty and Dvorak.

The intent of the Dvorak - Qwerty ⌘ layout is to use Dvorak normally, changing to Qwerty when command is pressed.

This was working yesterday in Chrome 68, not working today in 69.
