Yes

Describe the issue you encountered:
While navigating from one GitHub page to another, the Cmd+T shortcut (New Tab) is ignored.

Expected behavior:
The shortcut should always be available, regardless of current state

• Platform (Win7, 8, 10? macOS? Linux distro?): macOS
• Brave Version: 0.12.0
• Steps to reproduce:
  1. Open a GitHub listing page, e.g. https://github.com/brave/browser-laptop
  2. Click one of the files, e.g. LICENSE.txt
  3. Quickly, while the loading is still happening, press Cmd+T. I can reproduce the bug consistently if I press Cmd+T as quickly as I can after clicking the link.

@bridiver I think this will be fixed with your menu fix?

[bridiver]

I think so. I have seen similar issues with keyboard shortcuts and I can't replicate this one or the others with the menu fix

I will mark this as fixed in 0.12.1 and it can be tested / re-opened if not.
